Introduction

Background

Globally, the 20th century was marked by: (a) two devastating World Wars; (b) the Great Depression of the 1930s; (c) the end of vast colonial empires; (d) rapid advances in science and technology, from the first airplane flight at Kitty Hawk, North Carolina (US) to the landing on the moon; (e) the Cold War between the Western alliance and the Warsaw Pact nations; (f) a sharp rise in living standards in North America, Europe, and Japan; (g) increased concerns about environmental degradation including deforestation, energy and water shortages, declining biological diversity, and air pollution; (h) the onset of the AIDS epidemic; and (i) the ultimate emergence of the US as the only world superpower. The planet's population continues to explode: from 1 billion in 1820 to 2 billion in 1930, 3 billion in 1960, 4 billion in 1974, 5 billion in 1987, 6 billion in 1999, 7 billion in 2012, and 8 billion in 2022. For the 21st century, the continued exponential growth in science and technology raises both hopes (e.g., advances in medicine and agriculture) and fears (e.g., development of even more lethal weapons of war).

Geography

Geographic overview

The surface of the Earth is approximately 70.9% water and 29.1% land. The former portion constitutes the World Ocean, the single largest feature of the planet and one that connects all places on the globe. The World Ocean is divided by the intervening continental landmasses into five major ocean basins, which are in decreasing order of size: the Pacific, Atlantic, Indian, Southern, and Arctic. The World Factbook describes each of these five as oceans. Given the significant differences in direction and temperature of major ocean currents, as well as the effects of the major air masses above them, the Pacific and Atlantic Oceans are generally divided at the equator into the North and South Pacific Oceans and the North and South Atlantic Oceans, thus creating seven major water bodies - the so-called "Seven Seas."

Some 97.5% of the Earth's water is saltwater. Of the 2.5% that is fresh, about two-thirds is frozen mostly locked up in the Antarctic ice sheets and mountain glaciers worldwide. If all the surface ice on earth fully melted, the sea level would rise about 70 m (230 ft).

In a 100-year period, a water molecule spends 98 years in the ocean, 20 months as ice, about two weeks in lakes and rivers, and less than a week in the atmosphere. Groundwater can take 50 years to just traverse 1 km (0.6 mi).

Earth's land portion is generally divided into several, large, discrete landmasses termed continents. Depending on the convention used, the number of continents can vary from five to seven. The most common classification recognizes seven, which are (from largest to smallest): Asia, Africa, North America, South America, Antarctica, Europe, and Australia. Asia and Europe are sometimes lumped together into a Eurasian continent resulting in six continents. Alternatively, North and South America are sometimes grouped as simply the Americas, resulting in a continent total of six (or five, if the Eurasia designation is used).

North America is commonly understood to include the island of Greenland, the isles of the Caribbean, and to extend south all the way to the Isthmus of Panama. The easternmost extent of Europe is generally defined as being the Ural Mountains and the Ural River; on the southeast the Caspian Sea; and on the south the Caucasus Mountains, the Black Sea, and the Mediterranean. Portions of five countries - Azerbaijan, Georgia, Kazakhstan, Russia, and Turkey - fall within both Europe and Asia, but in every instance the larger section is in Asia. These countries are considered part of both continents. Armenia and Cyprus, which lie completely in Western Asia, are geopolitically European countries.

Asia usually incorporates all the islands of the Philippines, Malaysia, and Indonesia. The islands of the Pacific are often lumped with Australia into a "land mass" termed Oceania or Australasia. Africa's northeast extremity is frequently delimited at the Isthmus of Suez, but for geopolitical purposes, the Egyptian Sinai Peninsula is often included as part of Africa.

Although the above groupings are the most common, different continental dispositions are recognized or taught in certain parts of the World, with some arrangements more heavily based on cultural spheres rather than physical geographic considerations.

Based on the seven-continent model, and grouping islands with adjacent continents, Africa has the most countries with 54. Europe contains 49 countries and Asia 48, but these two continents share five countries: Azerbaijan, Georgia, Kazakhstan, Russia, and Turkey. North America consists of 23 sovereign states, Oceania has 16, and South America 12. In total, there are 197 countries recognized by the United States.

Three of the states described above – France, Netherlands, and the United Kingdom – consist of smaller political entities that are referred to as countries. France considers French Polynesia an overseas country; the Kingdom of the Netherlands refers to all four of its constituent parts (Netherlands [proper], and the islands of Aruba, Curacao, and Sint Maarten) as countries; and the United Kingdom comprises the countries of England, Wales, Scotland, and Northern Ireland. While not recognized as sovereign states, The World Factbook does include descriptive entries for the French and Dutch island "countries."

The World from space: Earth is the only planet in the Solar System to have water in its three states of matter: liquid (oceans, lakes, and rivers), solid (ice), and gas (water vapor in clouds). From a distance, Earth would be the brightest of the eight planets in the Solar System; this luminous effect would be because of the sunlight reflected by the planet's water.

Earth is also the only planet in the Solar System known to be active with earthquakes and volcanoes due to plate tectonics; these events form the landscape, replenish carbon dioxide into the atmosphere, and erase impact craters caused by meteors.

Earth has a slight equatorial bulge - a difference between its equatorial and polar diameters - because of the centrifugal force exerted by the rotation of the planet about its axis. The equatorial diameter is 12,756 km, but the polar diameter is 12,714 km; this results in the Earth's circumference at the equator being 40,075 km, while the polar circumference is 40,008 km.

The physical World: The Earth is composed of three layers: the outer lithosphere (with its crust and uppermost solid mantle), the mantle (the thickest layer, with distinct upper and lower layers), and the core (with an outer (liquid) and inner (solid) core). Researchers have discovered that a transition zone (at a depth of 410-660 km (255-410 mi)) between the upper and lower mantle may well be hydrous (water-bearing). But this hydrous rock would neither feel wet nor drip water. At that depth, high temperatures and pressures structurally transform a mineral called olivine into another mineral ringwoodite - and ringwoodite can incorporate water, but not water in a liquid, solid, or gas form. The high temperatures and pressures cause: 1) water molecules to split, creating hydroxide ions (hydrogen and oxygen atoms bound together), and 2) create structural changes in ringwoodite so that it is able to contain hydroxide ions. Ringwoodite can hold 1 to 3% of its weight in hydroxide ions. Considering that the 250 km-transition zone is about 7% of the Earth's mass (the crust, by comparison, is only about 1%), it could include at least as much (if not several times more) water than all of the Earth's oceans.

Land boundaries

The land boundaries in The World Factbook total 279,035.5 km (not counting shared boundaries twice); two nations, China and Russia, each border 14 other countries

Note 1: the total is actually misleading in terms of accuracy, since one cannot accurately measure every river meander along a boundary; a number rounded slightly higher - to 280,000 km - makes more sense and has been coordinated with and approved by the US State Department

Note 2: 46 nations and other areas are landlocked, these include: Afghanistan, Andorra, Armenia, Austria, Azerbaijan, Belarus, Bhutan, Bolivia, Botswana, Burkina Faso, Burundi, Central African Republic, Chad, Czechia, Eswatini, Ethiopia, Holy See (Vatican City), Hungary, Kazakhstan, Kosovo, Kyrgyzstan, Laos, Lesotho, Liechtenstein, Luxembourg, Macedonia, Malawi, Mali, Moldova, Mongolia, Nepal, Niger, Paraguay, Rwanda, San Marino, Serbia, Slovakia, South Sudan, Switzerland, Tajikistan, Turkmenistan, Uganda, Uzbekistan, West Bank, Zambia, Zimbabwe; two of these, Liechtenstein and Uzbekistan, are doubly landlocked

Note 3: worldwide, some one-quarter of interior (non-coastal) borders are rivers; South America with 43% leads the continents, followed by North America with 32%, Africa with 30%, Europe with 23%, and Asia with 18%; Australia has no interior national river borders

Maritime claims

A variety of situations exist, but in general, most countries make the following claims measured from the mean low-tide baseline as described in the 1982 UN Convention on the Law of the Sea: territorial sea - 12 nm, contiguous zone - 24 nm, and exclusive economic zone - 200 nm; additional zones provide for exploitation of continental shelf resources and an exclusive fishing zone; boundary situations with neighboring states prevent many countries from extending their fishing or economic zones to a full 200 nm

Natural resources

The rapid depletion of nonrenewable mineral resources, the depletion of forest areas and wetlands, the extinction of animal and plant species, and the deterioration in air and water quality pose serious long-term problems

Irrigated land

3,242,917 km² (2012 est.)

Major lakes (area km²)

Top ten largest natural lakes: Caspian Sea (Azerbaijan, Iran, Kazakhstan, Russia, Turkmenistan) 374,000 km²; Lake Superior (Canada, United States) 82,100 km²; Lake Victoria (Kenya, Tanzania, Uganda) 62,940 km²; Lake Huron (Canada, United States) 59,600 km²; Lake Michigan (United States) 57,750 km²; Lake Tanganyika (Burundi, Democratic Republic of the Congo, Tanzania, Zambia) 32,000 km²; Great Bear Lake (Canada) 31,328 km²; Lake Baikal (Russia) 31,500 km²; Lake Malawi (Malawi, Mozambique, Tanzania) 22,490 km²; Great Slave Lake (Canada) 28,568 km²

Note 1: the areas of the lakes are subject to seasonal variation; only the Caspian Sea is saline, the rest are fresh water

Note 2: Lakes Huron and Michigan are technically a single lake because the flow of water between the Straits of Mackinac that connects the two lakes keeps their water levels at near-equilibrium; combined, Lake Huron-Michigan is the largest freshwater lake by surface area in the World

Note 3: if ranked by water volume, the Caspian Sea would still be first, but it would be followed Lakes Baikal, Tanganyika, Superior, and Malawi; Lake Superior contains more water than the other four North American Great Lakes (Erie, Huron, Michigan, Ontario) combined

Top ten longest rivers: Nile (Africa) 6,650 km; Amazon (South America) 6,436 km; Yangtze (Asia) 6,300 km; Mississippi-Missouri (North America) 6,275 km; Yenisey-Angara (Asia) 5,539 km; Huang He/Yellow (Asia) 5,464 km; Ob-Irtysh (Asia) 5,410 km; Congo (Africa) 4,700 km; Amur (Asia) 4,444 km; Lena (Asia) 4,400 km

Note: there are 21 countries without rivers: 3 in Africa (Comoros, Djibouti, Libya), 1 in the Americas (Bahamas), 8 in Asia (Bahrain, Kuwait, Maldives, Oman, Qatar, Saudi Arabia, United Arab Emirates, Yemen), 3 in Europe (Malta, Monaco, Holy See), 6 in Oceania (Kiribati, Marshall Islands, Nauru, Niue, Tonga, Tuvalu); these countries also do not have natural lakes

Major watersheds (area km²)

Summary statement: a watershed is a drainage basin on an area of land where precipitation collects and drains off into a common outlet, such as into a river, bay, or other body of water; oceans ultimately take in the drainage from 83% of all land area; the remaining 17% of the land drains into internal (endorheic) basins, e.g., the Caspian Sea; The World Factbook lists 51 different watersheds across 102 countries; of these, 18 are in Asia, 9 in Europe, 9 in Africa, 8 in North and Central America, 5 in South America, and 2 in Australia; all watersheds with an area of at least 500,000 km² have been included along with a number of smaller, regionally significant watersheds; together, these watersheds represent the surface hydrology water flows that are the World's primary sources of fresh water for individual consumption, industry, and agriculture

Major aquifers

Summary statement: aquifers are underground layers of water-bearing permeable rock formations; they include alluvial formations such as unconsolidated sand and gravel aquifers, sedimentary rock formations of sandstone and karst (carbonate rocks such as limestone) aquifers, as well as volcanic aquifers, and basement aquifers (igneous and metamorphic rocks that underlie sedimentary and volcanic rock sequences); groundwater from aquifers can be extracted using a water well; The World Factbook lists 37 major aquifers across 52 countries; of these, 13 are in Africa, 10 in Asia, 5 in North America, 3 in South America, 4 in Europe, and 2 in Australia; although aquifers can vary in size, the major aquifers listed in The Factbook contain the bulk of the stored volume of groundwater; the fresh water held in these aquifers represents more than 30% of the World's fresh water; in the US, groundwater is primarily used for irrigation and globally, 70% of groundwater withdrawn is used for agriculture; groundwater also supplies almost half of all drinking water worldwide

Population distribution

Six of the world's seven continents are widely and permanently inhabited; Asia is easily the most-populous continent with about 60% of the world's population (China and India together account for over 35%); Africa comes in second with over 15% of the earth's populace, Europe has about 10%, North America 8%, South America almost 6%, and Oceania less than 1%; the harsh conditions on Antarctica prevent any permanent habitation

Natural hazards

Large areas subject to severe weather (tropical cyclones); natural disasters (earthquakes, landslides, tsunamis, volcanic eruptions)

Volcanism: volcanism is a fundamental driver and consequence of plate tectonics, the physical process reshaping the Earth's lithosphere; the World is home to more than 1,500 potentially active volcanoes, with over 500 of these having erupted in historical times; an estimated 500 million people live near these volcanoes; associated dangers include lava flows, lahars (mudflows), pyroclastic flows, ash clouds, ash fall, ballistic projectiles, gas emissions, landslides, earthquakes, and tsunamis; in the 1990s, the International Association of Volcanology and Chemistry of the Earth's Interior, created a list of 16 Decade Volcanoes worthy of special study because of their great potential for destruction: Avachinsky-Koryaksky (Russia), Colima (Mexico), Etna (Italy), Galeras (Colombia), Mauna Loa (United States), Merapi (Indonesia), Nyiragongo (Democratic Republic of the Congo), Rainier (United States), Sakurajima (Japan), Santa Maria (Guatemala), Santorini (Greece), Taal (Philippines), Teide (Spain), Ulawun (Papua New Guinea), Unzen (Japan), Vesuvius (Italy); see second note under "Geography - note"

Volcano statistics and superlatives:

Countries with the most volcanoes (Holocene Epoch, the past 12,000 years): United States (162), Japan (122), Indonesia (120), Russia (117), Chile (91); note - roughly 1,350 volcanoes have erupted over this time period; about 40-50 eruptions are ongoing at any one time; the frequency of volcanoes has not increased

Longest erupting volcano: Santa Maria volcano in Guatemala has been constantly erupting since 22 June 1922; note - the Yasur volcano on Tanna Island in Vanuatu was observed to be erupting by Captain Cook in 1774 and has been in constant activity since then, but it is not cited since it has no clear start date; research (tephra stratigraphy and radiocarbon dating) shows that activity may have begun on Yasur ca. A.D. 1270 and so has persisted for over 750 years

Highest volcano (above sea level): Nevado Ojos del Salado (6,893 m; 22,615 ft) on the Chile-Argentina border is the World's highest volcano above sea level and the highest peak in Chile

Highest volcano (from base): Mauna Kea (United States) is the World's tallest mountain as measured from base to summit; the peak of this volcanic colossus lies on the island of Hawaii, but its base begins more than 70 km offshore and at a depth of about 6,000 m; total height estimates range from 9,966 m to 10,203 m

Wonders of the World

The Seven Wonders of the Ancient World:

The conquests of Alexander the Great (r. 336-323 B.C.) in the fourth century B.C. fostered the spread of Greek culture to the lands bordering the eastern Mediterranean and through much of the Middle East, ushering in what is today referred to as the Hellenistic Period (323-31 B.C.). Guidebooks compiled by Hellenistic sightseers focused on outstanding monuments in those parts of the world now brought into the Hellenistic sphere: Persia, Egypt, and Babylon. Generally, seven were emphasized since that number was considered magical, perfect, and complete. Not all Wonders lists from ancient times agreed completely, but generally six of the seven consistently appeared (the massive Walls of Babylon sometimes substituted for the Lighthouse of Alexandria). The seven described below represent the “classic” Seven Wonders most often cited.

1\. The Great Pyramid of Egypt

The oldest of the Seven Wonders, the Great Pyramid is the only one that remains largely intact. Commissioned by the Pharaoh Khufu (r. ca. 2589-2566 B.C.), it is the largest of the three pyramids at Giza. It served as the ruler’s tomb and was built over a period of some 20 years, concluding about 2560 B.C. Estimated to have been 146.5 m tall when completed, it was the tallest man-made structure in the world for over 3,800 years (until the 14th century A.D.). Most of the original limestone casing stones that formed the outer smooth surface of the pyramid are gone. Today, the pyramid’s height is about 139 m.

2\. The Hanging Gardens of Babylon

This is the only one of the ancient Seven Wonders for which a definitive location has never been established. There are no surviving Babylonian texts mentioning the Gardens, nor have any archeological remains ever been discovered in today’s Iraq. According to tradition, the Gardens were a remarkable feat of engineering with an ascending series of mud-brick-tiered gardens containing a variety of trees, shrubs, and vines that when viewed from below resembled a leafy green mountain. The Gardens are frequently attributed to the Neo-Babylonian King Nebuchadnezzar II (r. 605-562 B.C.), who had them built for his Median wife Queen Amytis, who missed the green hills and valleys of her homeland.

3\. The Temple of Artemis (Artemision) at Ephesus

This Greek temple at Ephesus (3 km southwest of Selcuk in present-day western Turkey), dedicated to the goddess Artemis, was completely rebuilt twice: once after a 7th century B.C. flood and then following a 356 B.C. act of arson. In its final form it was judged to be one of the Seven Wonders and it survived for 600 years. The magnificent building was composed entirely of marble. Its massive dimensions were reported as 130 m by 69 m, with 127 columns, each some 18 m tall. The Temple was damaged in a Gothic raid in A.D. 268 and finally closed by Christians in the early-to-mid 5th century. The structure was dismantled in succeeding centuries and today almost nothing of the Temple remains.

4\. The Mausoleum of Halicarnassus

Constructed in about 350 B.C., the Mausoleum of Halicarnassus was located on the site of the present-day city of Bodrum in southwestern Turkey. It was the tomb of Mausolus, a Persian ruler, and his wife. (It is from the ruler’s name that the term mausoleum is derived.) The structure stood about 45 m high and took some 20 years to complete. A series of earthquakes between the 12th and 15th centuries A.D. devastated the structure, the last of the original Seven Wonders to be destroyed.

5\. The Colossus of Rhodes

This statue of the Greek sun god Helios, constructed to celebrate Rhodes’ successful repulse of a siege, was made of iron tie bars to which brass or bronze plates were attached to form a skin. Contemporary descriptions list its height at about 70 cubits or some 33 m – approximately the same height as the Statue of Liberty from heel to top of head (34 m) – thus making it the tallest statue in the ancient world. Completed in about 280 B.C. at the entrance to Rhodes harbor, the monument only stood for approximately 54 years until it toppled in a 226 B.C. earthquake. The impressive remains lay on the ground for over 800 years before finally being sold for scrap.

6\. The Lighthouse (Pharos) of Alexandria

Completed around 275 B.C., the Alexandria Lighthouse stood on Pharos Island at the entrance to the Egyptian port city for some 1,600 years! It was severely damaged by three earthquakes between A.D. 956 and 1323, when it was deactivated. We have a fairly good idea of the shape of the structure since it appears on a number of ancient coins. A solid square base, which made up about half of the height, supported an octagonal middle section, and a cylindrical top. The height of the structure is thought to have been at least 100 m and perhaps as high as 140 m. (The tallest lighthouse in the world today is the Jeddah Light in Saudi Arabia, which stands at 133 m.) At its apex stood a mirror that reflected sunlight during the day; a fire burned at night. Since it could be seen at a very great distance, the Pharos light served as a reassuring beacon for mariners from all parts of the Mediterranean.

7\. The Statue of Zeus at Olympia in Greece

The giant seated statue of the king of the Greek gods in the sanctuary of Olympia was completed by the Greek sculptor Phidias in approximately 435 B.C. Roughly 13 m tall, it was constructed of ivory plates and gold panels on a wooden framework; the god’s throne was ornamented with ebony, ivory, gold, and precious stones. With the rise of Christianity, the sanctuary at Olympia fell into disuse; the details of the statue’s final destruction are unknown.

Note: The Lighthouse of Alexandria may have been the last of the Wonders to be completed (ca. 275 B.C.) and the Colossus of Rhodes was the first to be destroyed in about 226 B.C., so the Seven Wonders existed at the same time for only some 50 years in the middle of the third century B.C.

The New Seven Wonders of the World:

A private initiative to come up with a new list for seven of the world’s wonders sprang up early in the new Millennium. Worldwide balloting – via the Internet or by telephone – took place covering a list of 200 existing monuments. Reportedly over 100 million votes were cast over a period of several years and the final list was announced on 7-7-2007. Even though the polling was unscientific, the seven “winners” were a worthy compilation of extraordinary Wonders to be found around the world. All seven of the New Wonders are inscribed as UNESCO World Heritage Sites and are frequently cited in the literature.

1\. Chichen Itza, Yucatan, Mexico

This archeological site includes the impressive remains of a large pre-Columbian Maya city that flourished from ca. A.D. 600-1100. Among the outstanding structures at the site are the massive Temple of the Warriors complex, an Observatory (El Caracol), the Great Ball Court, and the Sacred Cenote (sinkhole) where offerings were made. The most famous building, however, is the step-pyramid known as the Temple of Kukulcan that dominates the center of the site and serves as the symbol of Chichen Itza. The pyramidal structure is 24 m high; the crowning temple adds another 6 m. Although located in the dense jungles of Yucatan, it remains one of the most visited tourist sites in Mexico.

2\. The Colosseum, Rome, Italy

Construction began with the Roman Emperor Vespasian in A.D. 72 and was completed by his son Titus in A.D. 80. Some further modifications were made by Domitian (A.D. 81-96). The three emperors make up the Flavian Dynasty, thus providing the alternate name for the structure as the Flavian Amphitheater. The massive structure is estimated to have seated, on average, about 65 thousand spectators and was most famously used for gladiatorial contests and public spectacles. Substantially ruined by earthquakes and thieves who looted much of the stone, the structure nonetheless remains an iconic symbol of Rome. The Colosseum is one of the most popular tourist attractions in the World.

3\. Christ the Redeemer Statue, Rio de Janeiro, Brazil

Built between 1922 and 1931, the 30-meter-tall sculpture is reputed to be the largest Art Deco statue in the World. Its pedestal provides another 8 m in height and the arms stretch out to 28 m. Constructed of reinforced concrete and soapstone, the statue has become the cultural icon not only of Rio but also of Brazil.

4\. Great Wall, China

The name refers to a remarkable series of fortification systems that stretched across the northern historical borders of China and served as protection against various nomadic peoples. The earliest of these walls date to the 7th century B.C.; certain stretches began to be linked in the 3rd century B.C. and successive dynasties added to or maintained various sections of the walls. The best known and best-preserved portions of the wall are those built by the Ming Dynasty (1368-1644). An archeological survey revealed that the Wall and all its associated branches measures 21,196 km. Winding through amazingly varied terrain, the Great Wall is acknowledged as one of the most impressive architectural feats in history.

5\. Machu Picchu, Cuzco Region, Peru

Perhaps the most spectacular archeological site in the Americas, the Inca citadel of Machu Picchu, situated on a 2,430 m Andean mountain ridge, is now thought to have been erected as an estate for the Inca Emperor Pachacuti (r. 1438-1471). Additionally, it may also have served as a religious sanctuary. Built between about 1450 and 1460, it was abandoned approximately a century later, at the time of the Spanish conquest. Construction was carried out in the classic Inca style of polished, dry-stone, fitted walls. Some 750 people lived at this royal estate, most of them support staff to the nobility. The site is roughly divided into an agricultural sector (with myriad terraces for raising crops) and an urban sector. The latter is composed of an upper town (with temples) and a lower town (with warehouses). Some of the religious monuments include: the Intiwatana (a carved, ritual stone that served as a type of sundial and that is referred to as “The Hitching Post of the Sun”); the Torreon or Temple of the Sun, a small tower that likely served as a type of observatory; and the Intimachay, a sacred cave with a masonry entrance.

6\. Petra, Ma’an, Jordan

Petra is believed to have been established in the 4th century B.C. as the capital of the Nabataean Kingdom, an entity that grew fabulously wealthy as the nexus of trade routes in the southern Levant. The kingdom retained its independence until annexed by the Roman Empire in A.D. 106. The city is justifiably famous for two things, its stunning rock-cut architecture and its water conduit system, which allowed the Nabataeans to control and store the water supply in this desert region and create an artificial oasis. At its peak in the 1st century A.D., the city may have had a population of 20 thousand.

7\. Taj Mahal, Agra, Uttar Pradesh, India

This gorgeous ivory-white mausoleum – described as “one of the universally admired masterpieces of the World’s heritage” – was commissioned in 1632 by Shah Jahan (r. 1628-1658) as the final resting place for his favorite wife, Mumtaz Mahal. The building also houses the tomb of Shah Jahan himself. The Taj Mahal is the centerpiece of an entire 17-hectare complex that also includes a guest house, a mosque, and formal gardens. The entire project was not completed until about 1653. The Taj Mahal remains one of the most visited tourist sites in the World.

Note: The Great Pyramid of Egypt, the only surviving Wonder of the ancient Seven, received an honorary status among the New Seven Wonders. Its inclusion enabled a Wonder to be listed for five of the six habitable continents (all but Australia).

The World Factbook's Seven Natural Ultra-Wonders of the World:

While all of the above Wonders are indeed outstanding, their presence in any type of list is entirely subjective. There are many other fabulous sites around the world that are equally worthy of being designated as Wonders. (An example is the inclusion of Chichen Itza from Mexico. While it is spectacular, it became a 'Wonder' for its popularity as a tourist site. Equally worthy in the same country is Teotihuacan, a far larger site outside of Mexico City that has two immense pyramids that dwarf the one at Chichen Itza.)

Taking these considerations into account, The World Factbook has come up with a Seven Wonders list that is indisputable, i.e., a list derived in a completely objective manner. A decision was made to focus on natural wonders and not anything man-made. These Wonders are all the biggest in their respective categories (they cannot be topped) and so there can be no dispute with the choice, therefore the 'ultra' designation. This fact distinguishes the Factbook listing from other Seven Natural Wonders lists that have been compiled in the past.

1\. Amazonia

A trans-national Wonder that is: a. the World's largest collection of land biodiversity, b. the World's largest rainforest, and c. includes the World's largest swamp in the Amazon River floodplain; mostly in Brazil, Peru, and Colombia, but also in Venezuela, Ecuador, Bolivia, Guyana, Suriname, and French Guiana.

2\. Central Indo-Pacific Region

A Wonder hotspot that is the World's largest collection of marine biodiversity; best represented by the Coral Triangle in the tropical waters around the Philippines, Indonesia, Malaysia, Papua New Guinea, the Solomon Islands, and Timor-Leste; as well as by the Great Barrier Reef (the World's largest reef) in Australia.

3\. The Aurora (Aurora Borealis and Aurora Australis; aka the Polar Lights)

The World's largest light display that never ceases to awe; seen in countries of the northern latitudes, as well as those of the southern latitudes and Antarctica.

4\. Mount Everest and the Himalayas

The World's tallest mountain and mountain range above sea level that stretches across Nepal, China (Tibet), India, Pakistan, and Bhutan (see alternate below).

5\. Victoria Falls

The World's largest unbroken waterfall on the border between Zambia and Zimbabwe (see alternates below).

6\. Sahara

The World's largest hot desert that spreads across Algeria, Chad, Egypt, Libya, Mali, Mauritania, Morocco, Niger, Sudan, and Tunisia (see alternate below).

7\. Animal Migrations

The Earth is full of astounding migrations – occurring daily, seasonally, or annually – that are truly awe-inspiring natural wonders. A few extraordinary examples are: a. the diel vertical migrations (DVM, the World's largest animal migration in terms of biomass and number of animals participating), which occur twice daily in all the oceans when zooplankton (microscopic animals) and fish rise to near the surface at night to feed on phytoplankton (microscopic plants) and then with the return of day dive back into the depths to hide in dark waters; b. the Arctic tern's annual round trip of 71,000 km (from the Northern Hemisphere to the Southern Hemisphere and back (the World's longest avian migration); or c. the 22,000 km annual migration of the humpback whale (World's longest mammal migration).

Alternates

Mountain alternate (no. 4). If measured strictly from base to peak, then the World's tallest and largest mountains would be on the Island of Hawaii, which includes both the World's tallest mountain [Mauna Kea] and the World's largest active volcano and most voluminous mountain [Mauna Loa]); United States (Hawaii).

Waterfall alternate (no. 5). What constitutes the 'biggest' waterfall(s) can be approached in a number of ways. Depending on one's viewpoint, Iguazu Falls (World's largest waterfall system (275 drops)) in Argentina and Brazil, or Angel Falls (World's tallest waterfall) in Venezuela could substitute.

Desert alternate (no. 6). If a desert is defined as a barren area where little precipitation occurs, then Antarctica with the World's largest polar desert would certainly qualify; it is about 1.5 times the size of the Sahara. The southern continent does not belong to any one country but is a condominium governed by parties to the Antarctic Treaty.

Note: A question might arise, how about the World's largest canyon? The Grand Canyon (United States, Arizona) is sometimes mentioned as a Wonder of the World, but 'largest' canyons can be notoriously difficult to define and measure. Does one go by length, depth, or total area of canyon system? Then too, there are largely inaccessible canyons in the Himalayas that have never been properly surveyed and massive canyons are known to exist in some ice-covered parts of Greenland and Antarctica. Therefore, it is not possible to come up with a superlative canyon.

Geography - note

Note 1: the World is now thought to be about 4.55 billion years old, just about one-third of the 13.8-billion-year age estimated for the universe; the earliest widely accepted date for life appearing on Earth is 3.48 billion years ago, but this date is conservative and may get pushed back further

Note 2: although earthquakes can strike anywhere at any time, the vast majority occur in three large zones of the Earth; the world's greatest earthquake belt, the Circum-Pacific Belt (popularly referred to as the Ring of Fire), is the zone of active volcanoes and earthquake epicenters bordering the Pacific Ocean; about 90% of the World's earthquakes (81% of the largest earthquakes) and some 75% of the World's volcanoes occur within the Ring of Fire; the belt extends northward from Chile, along the South American coast, through Central America, Mexico, the western US, southern Alaska and the Aleutian Islands, to Japan, the Philippines, Papua New Guinea, island groups in the southwestern Pacific, and New Zealand

The second prominent belt, the Alpide, extends from Java to Sumatra, northward along the mountains of Burma, then eastward through the Himalayas, the Mediterranean, and out into the Atlantic Ocean; it accounts for about 17% of the world's largest earthquakes; the third important belt follows the long Mid-Atlantic Ridge

Note 3: information on the origin sites for many of the World's major food crops may be found in the "Geography - note" for the following countries: Argentina, Bolivia, Brazil, China, Ecuador, Ethiopia, Indonesia, Mexico, Papua New Guinea, Paraguay, Peru, and the United States

Major infectious diseases

Food or waterborne diseases: Typhoid fever \- An estimated 26 million cases of typhoid fever and 5 million cases of paratyphoid fever occur worldwide each year, causing 215,000 deaths. High-risk regions for typhoid and paratyphoid fever include Africa and Southeast Asia; lower-risk regions include East Asia, South America, and the Caribbean. Typhoid fever is a life-threatening illness caused by Salmonella Typhi bacteria. Paratyphoid fever is a life-threatening illness caused by Salmonella Paratyphi bacteria. The bacteria that cause typhoid fever are most often spread through contaminated food and water and person to person contact. Symptoms of typhoid fever include high fever, weakness, stomach pain, headache, constipation or diarrhea, cough, and loss of appetite. Typhoid fever can be fatal without appropriate antibiotic treatment. CDC recommends that all travelers (even short-term travelers) to affected areas be vaccinated against typhoid fever before travel.

Vectorborne diseases: Malaria \- In 2020, an estimated 627,000 people died of malaria—most were young children in sub-Saharan Africa. Nearly half the world’s population lives in areas at risk of malaria transmission in 87 countries and territories (see attached map). In 2020, malaria caused an estimated 241 million clinical episodes, and 627,000 deaths. An estimated 95% of deaths in 2020 were in the WHO African Region. The predominant parasite species is Plasmodium falciparum, which is the species that is most likely to cause severe malaria and death. Where malaria is found depends mainly on climatic factors such as temperature, humidity, and rainfall. Malaria is transmitted in tropical and subtropical areas, where Anopheles mosquitoes can survive and multiply, and malaria parasites can complete their growth cycle in the mosquitoes (“extrinsic incubation period”). Temperature is particularly critical. For example, at temperatures below 20°C (68°F), Plasmodium falciparum (which causes severe malaria) cannot complete its growth cycle in the Anopheles mosquito, and thus cannot be transmitted.

African Trypanosomiasis \- also known as “sleeping sickness”, is caused by microscopic parasites of the species Trypanosoma brucei. It is transmitted by the tsetse fly (Glossina species), which is found only in sub-Saharan Africa. Two morphologically indistinguishable subspecies of the parasite cause distinct disease patterns in humans: T. b. gambiense causes a slowly progressing African trypanosomiasis in western and central Africa and T. b. rhodesiense causes a more acute African trypanosomiasis in eastern and southern Africa. Control efforts have reduced the number of annual cases and for the first time in 50 years, the number of reported cases fell under 10,000 in 2009. In 2017–2018, fewer than 2000 cases were reported to WHO. The number of cases continue to drop and in 2020, fewer than 700 combined cases were reported to WHO; over 85% caused by T. b. gambiense and around 15% caused by T. b. rhodesiense. Sleeping sickness is curable with medication but is fatal if left untreated.

Dengue fever \- Dengue viruses are spread to people through the bite of an infected Aedes species (Ae. aegypti or Ae. albopictus) mosquito. Almost half of the world’s population, about 4 billion people, live in areas with a risk of dengue. Dengue is often a leading cause of illness in areas with risk. Each year, up to 400 million people get infected with dengue. Approximately 100 million people get sick from infection, and 40,000 die from severe dengue. Dengue has emerged as a worldwide problem since the 1960s. The disease is common in many popular tourist destinations in the Caribbean (including Puerto Rico), Central and South America, Southeast Asia, and the Pacific Islands (see attached regional maps). In the United States, local cases and limited spread of dengue does occur periodically in some states with hot, humid climates and Aedes mosquitoes.

Water contact diseases: Schistosomaisis - also known as bilharzia, is a disease caused by parasitic worms. In terms of impact this disease is second only to malaria as the most devastating parasitic disease (see attached map). Schistosomiasis is considered one of the neglected tropical diseases (NTDs). The parasites that cause schistosomiasis live in certain types of freshwater snails. The infectious form of the parasite, known as cercariae, emerge from the snail into the water. You can become infected when your skin comes in contact with contaminated freshwater. Most human infections are caused by Schistosoma mansoni, S. haematobium, or S. japonicum. Freshwater becomes contaminated by Schistosoma eggs when infected people urinate or defecate in the water. The eggs hatch, and if certain types of freshwater snails are present in the water, the parasites develop and multiply inside the snails. The parasite leaves the snail and enters the water where it can survive for about 48 hours. Schistosoma parasites can penetrate the skin of persons who are wading, swimming, bathing, or washing in contaminated water.

Respiratory diseases: Meningococcal meningitis \- Meningococcal disease occurs worldwide, with the highest incidence of disease found in the ‘meningitis belt’ of sub-Saharan Africa (see attached map). In this region, major epidemics occur every 5 to 12 years with attack rates reaching 1,000 cases per 100,000 population. Bacteria called Neisseria meningitidis cause meningococcal disease. About 1 in 10 people have these bacteria in the back of their nose and throat without being ill. This is called being ‘a carrier.’ Sometimes the bacteria invade the body and cause certain illnesses, which are known as meningococcal disease. Other regions of the world experience lower overall rates of disease and occasional outbreaks. Annual attack rates in these regions averages around 0.3 to 3 per 100,000 population. Risk factors for meningococcal disease outbreaks in Africa are not fully understood. However, the following characteristics create favorable conditions for meningococcal disease epidemics: Dry and dusty conditions during the dry season between December to June, Immunological susceptibility of the population, Travel and large population displacements, Crowded living conditions

Note 1: widespread ongoing transmission of a respiratory illness caused by the novel coronavirus (COVID-19) is occurring globally; older adults and people of any age with serious chronic medical conditions are at increased risk for severe disease; as of 23 August 2023, 769,806,130 confirmed cases of COVID-19 and 6,955,497 deaths had been reported to the World Health Organization; as of 23 August 2023, 70.5% of the World population had received at least one dose of COVID-19 vaccine

Note 2: on 31 August 2023, the US Centers for Disease Control and Prevention (CDC) issued a Travel Alert for some international destinations (see attached map) currently considered a high risk to travelers for circulating vaccine-derived polioviruses (cVDPV); vaccine-derived poliovirus (VDPV) is a strain of the weakened poliovirus that was initially included in oral polio vaccine (OPV) and that has changed over time and behaves more like the wild or naturally occurring virus; this means it can be spread more easily to people who are unvaccinated against polio and who come in contact with the stool or respiratory secretions, such as from a sneeze, of an “infected” person who received oral polio vaccine; the CDC recommends that before any international travel, anyone unvaccinated, incompletely vaccinated, or with an unknown polio vaccination status should complete the routine polio vaccine series; before travel to any high-risk destination, the CDC recommends that adults who previously completed the full, routine polio vaccine series receive a single, lifetime booster dose of polio vaccine

World biomes

Types of Biomes:

A biome is a biogeographical designation describing a biological community of plants and animals that has formed in response to a physical environment and a shared regional climate. Biomes can extend over more than one continent. Different classification systems define different numbers of biomes. The World Factbook recognizes the following seven biomes used by NASA: Tundra, Coniferous Forest, Temperate Deciduous Forest, Rainforest, Grassland, Shrubland, and Desert.

Tundra biome: The tundra is the coldest of the biomes. It also receives low amounts of precipitation, making the tundra similar to a desert. Tundra comes from the Finnish word tunturia, meaning "treeless plain". Tundra is found in the regions just below the ice caps of the Arctic, extending across North America, to Europe, and Siberia in Asia. Temperatures usually range between -40°C (-40 °F) and 18°C (64°F). The temperatures are so cold that there is a layer of permanently frozen ground below the surface, called permafrost. This permafrost is a defining characteristic of the tundra biome. In the tundra summers, the top layer of soil thaws only a few inches down, providing a growing surface for the roots of vegetation. This biome sees 150 to 250 mm (6 to 10 in) of rain per year. Vegetation in the tundra has adapted to the cold and the short growing season and consists of lichens, mosses, grasses, sedges, shrubs, but almost no trees due to short growing season and permafrost.

Coniferous Forest biome: The coniferous forest is sandwiched in between the tundra to the north and the deciduous forest to the south. Coniferous forest regions have cold, long, snowy winters, and warm, humid summers; well-defined seasons; and at least four to six frost-free months. The average temperature in winter ranges from -40°C (-40°F) to 20°C (68°F). The average summer temperatures are usually around 10°C (50°F). 300 to 900 mm (12 to 35 in) of rain per year can be expected in this biome. Vegetation consists of trees that produce cones and needles called, coniferous-evergreen trees. Some needles remain on the trees all year long. Some of the more common conifers are spruces, pines, and firs.

Temperate Deciduous Forest biome: Temperate deciduous forests are located in the mid-latitude areas which means that they are found between the polar regions and the tropics. The deciduous forest regions are exposed to warm and cold air masses, which cause this area to have four seasons. Hot summers and cold winters are typical in this biome. The average daily temperatures range between -30°C (-22°F) and 30°C (86°F) with a yearly average of 10°C (50°F). On average, this biome receives 750 to 1,500 mm (30 to 59 in) of rain per year. Vegetation includes broadleaf trees (oaks, maples, beeches), shrubs, perennial herbs, and mosses. Temperate deciduous forests are most notable for their transitioning through four seasons. Leaves change color (or senesce) in autumn, fall off in the winter, and grow back in the spring; this adaptation allows plants to survive cold winters.

Rainforest biome: The rainforest biome remains warm all year and must stay frost-free. The average daily temperatures range from 20°C (68°F) to 25°C (77°F). Rainforests receive the most rain of all of the biomes in a year! A typical year sees 2,000 to 10,000 mm (79 to 394 in) of rain per year. Vegetation typically includes vines, palm trees, orchids, ferns. There are two types of rainforests, tropical and temperate. Tropical rainforests are found closer to the equator and temperate rainforests are found farther north near coastal areas. The majority of common houseplants come from the rainforest.

Grassland biome: Grasslands are generally open and continuous, fairly flat areas of grass. They are often located between temperate forests at high latitudes and deserts at subtropical latitudes. Found on every continent except Antarctica. Depending on latitude, the annual temperature range can be between -20°C (-4°F) to 30°C (86°F). Grasslands receive around 500 to 900 mm (20 to 35 in) of rain per year. Tropical grasslands have dry and wet seasons that remain warm all the time. Temperate grasslands have cold winters and warm summers with some rain. Vegetation is dominated by grasses but can include sedges and rushes along with some legumes (clover) and herbs. The grasses die back to their roots annually and the soil and the sod protect the roots and the new buds from the cold of winter or dry conditions. A few trees may be found in this biome along the streams, but not many due to the lack of rainfall.

Shrubland biome: Shrublands include regions such as chaparral, woodland and savanna, and are composed of shrubs or short trees. Many shrubs thrive on steep, rocky slopes, but there is usually not enough rain to support tall trees. Shrublands are the areas that are located in west coastal regions between 30° and 40° North and South latitude. These regions are usually found surrounding deserts and grasslands. The summers are hot and dry with temperatures reaching up to 38°C (100°F). In the winter, temperatures stay around -1 °C (30°F) and are cool and moist. Annual rainfall in the shrublands varies greatly but generally 200 to 1,000 mm (8 to 40 in) of rain per year can be expected. Vegetation comprises aromatic herbs (sage, rosemary, thyme, oregano), shrubs, acacia, chamise, grasses. Plants have adapted to fire caused by the frequent lightning that occurs in the hot, dry summers.

Desert biome: Desert biomes are the driest of all the biomes. In fact, the most important characteristic of a desert is that it receives very little rainfall. Deserts get about 250 mm (10 in) of rain per year - the least amount of rain of all of the biomes. During the day, desert temperatures rise to an average of 38°C (100°F). At night, desert temperatures fall to an average of -4°C (about 25°F). Vegetation is sparse consisting of cacti, small bushes, short grasses. Perennials survive for several years by becoming dormant and flourishing when water is available. Annuals are referred to as ephemerals because some can complete an entire life cycle in weeks. Since desert conditions are so severe, the plants that live there need to have adaptations to compensate for the lack of water. Some plants, such as cacti, store water in their stems and use it very slowly, while others like bushes conserve water by growing few leaves or by having large root systems to gather water.

Country name

Note: countries with names connected to animals include: Albania "Land of the Eagles"; Anguilla (the name means "eel"); Bhutan "Land of the Thunder Dragon"; Cameroon (the name derives from "prawns"); Cayman Islands (named after the caiman, a marine crocodile); Faroe Islands (from Old Norse meaning "sheep"); Georgia "Land of the Wolves"; Italy "Land of Young Cattle"; Kosovo "Field of Blackbirds"; Sierra Leone "Lion Mountains"; Singapore "Lion City"

Capital

Time difference: there are 21 World entities (20 countries and 1 dependency) with multiple time zones: Australia, Brazil, Canada, Chile, Democratic Republic of Congo, Ecuador, France, Greenland (part of the Danish Kingdom), Indonesia, Kazakhstan, Kiribati, Mexico, Micronesia, Mongolia, Netherlands, New Zealand, Papua New Guinea, Portugal, Russia, Spain, United States

Note 1: in some instances, the time zones pertain to portions of a country that lie overseas

Note 2: in 1851, the British set their prime meridian (0° longitude) through the Royal Observatory at Greenwich, England; this meridian became the international standard in 1884 and thus the basis for the standard time zones of the World; today, GMT is officially known as Coordinated Universal Time (UTC) and is also referred to as "Zulu time"; UTC is the basis for all civil time, with the World divided into time zones expressed as positive or negative differences from UTC

Note 3: each time zone is based on 15° starting from the prime meridian; in theory, there are 24 time zones based on the solar day, but there are now upward of 40 because of fractional hour offsets that adjust for various political and physical geographic realities; see the Standard Time Zones of the World map included with the World and Regional Maps

Daylight saving time: some 67 countries - including most of the World's leading industrialized nations - use daylight savings time (DST) in at least a portion of the country; China, Japan, India, and Russia are major industrialized countries that do not use DST; Asia and Africa generally do not observe DST and it is generally not observed near the equator, where sunrise and sunset times do not vary enough to justify it; some countries observe DST only in certain regions; for example, only southeastern Australia observes it; in fact, only a minority of the World's population - about 20% - uses DST

Administrative divisions

197 countries, 69 dependent areas and other entities

Dependent areas

Australia dependencies: Ashmore and Cartier Islands, Christmas Island, Cocos (Keeling) Islands, Coral Sea Islands, Heard Island and McDonald Islands, Norfolk Island (6)

France dependencies: Clipperton Island, French Polynesia, French Southern and Antarctic Lands, New Caledonia, Saint Barthelemy, Saint Martin, Saint Pierre and Miquelon, Wallis and Futuna (8)

New Zealand dependency: Tokelau (1)

United States dependencies: American Samoa, Baker Island, Guam, Howland Island, Jarvis Island, Johnston Atoll, Kingman Reef, Midway Islands, Navassa Island, Northern Mariana Islands, Palmyra Atoll, Puerto Rico, Virgin Islands, Wake Island (14)

Legal system

The legal systems of nearly all countries are generally modeled upon elements of five main types: civil law (including French law, the Napoleonic Code, Roman law, Roman-Dutch law, and Spanish law); common law (including English and US law); customary law; mixed or pluralistic law; and religious law (including Islamic sharia law); an additional type of legal system - international law - governs the conduct of independent nations in their relationships with one another

International law organization participation

All members of the UN are parties to the statute that established the International Court of Justice (ICJ) or World Court; states parties to the Rome Statute of the International Criminal Court (ICCt) are those countries that have ratified or acceded to the Rome Statute, the treaty that established the Court; as of May 2019, a total of 122 countries have accepted jurisdiction of the ICCt (see Appendix B for a clarification on the differing mandates of the ICJ and ICCt)

Executive branch

Chief of state: there are 27 countries with royal families in the World, most are in Asia (13) and Europe (10), three are in Africa, and one in Oceania; monarchies by continent are as follows: Asia (Bahrain, Bhutan, Brunei, Cambodia, Japan, Jordan, Kuwait, Malaysia, Oman, Qatar, Saudi Arabia, Thailand, United Arab Emirates); Europe (Belgium, Denmark, Liechtenstein, Luxembourg, Monaco, Netherlands, Norway, Spain, Sweden, United Kingdom); Africa (Eswatini, Lesotho, Morocco); Oceania (Tonga)

Note 1: Andorra and the Holy See (Vatican) are also monarchies of a sort, but they are not ruled by royal houses; Andorra has two co-princes (the president of France and the bishop of Urgell) and the Holy See is ruled by an elected pope

Note 2: the sovereign of Great Britain is also the monarch for 14 of the countries (including Australia, Canada, Jamaica, New Zealand) that make up the Commonwealth; that brings to 43 the total number of countries with some type of monarchies

Legislative branch

There are 230 political entities with legislative bodies; of these 144 are unicameral (a single “house”) and 86 are bicameral (both upper and lower houses); note - while there are 197 countries in the World, 33 territories, possessions, or other special administrative units also have their own governing bodies

Flag description

While a "World" flag does not exist, the flag of the United Nations (UN) - adopted on 7 December 1946 - has been used on occasion to represent the entire planet; technically, however, it only represents the international organization itself; the flag displays the official emblem of the UN in white on a blue background; the emblem design shows a map of the World in an azimuthal equidistant projection centered on the North Pole, the image is flanked by two olive branches crossed below; blue was selected as the color to represent peace, in contrast to red usually associated with war; the map projection chosen includes all of the continents except Antarctica

Note 1: the flags of 12 nations: Austria, Botswana, Georgia, Jamaica, Japan, Laos, Latvia, Micronesia, Nigeria, North Macedonia, Switzerland, and Thailand have no top or bottom and may be flown with either long edge on top without any notice being taken

Note 2: the most common colors found on national flags are: red (including deep red; ~75%), white (~70%), and blue (including light blue; ~50%); these three colors are so prevalent that there are only two countries, Jamaica and Sri Lanka, that do not include one of them on their flag; the next three most popular colors are: yellow/gold and green (both ~45%) and black (~30%)

Note 3: flags composed of three colors are by far the most common type and, of those, the red-white-blue combination is the most widespread

United Nations flag:

National anthem

Name: virtually every country has a national anthem; most (but not all) anthems have lyrics, which are usually in the national or most common language of the country; states with more than one national language may offer several versions of their anthem

Note: the World's oldest national anthem is the "Het Wilhelmus" (The William) of the Netherlands, which dates to the 17th century; the first national anthem to be officially adopted (1795) was "La Marseillaise" (The Song of Marseille) of France; Japan claims to have the World's shortest national anthem, entitled "Kimigayo" (The Emperor's Reign), it consists of 11 measures of music (the lyrics are also the world's oldest, dating to the 10th century or earlier); the World's longest national anthem in terms of lyrics is that of Greece, "Ymnos eis tin Eleftherian" (Hymn to Liberty) with 158 stanzas - only two of which are used; the World's longest national anthem in terms of music is that of Uruguay, "Himno Nacional" (National Anthem of Uruguay) with 105 bars (almost five minutes) - generally only the first verse and chorus are sung; both Denmark and New Zealand have two official national anthems

Telecommunication systems

General assessment: Information, Communications, and Technology (ICT) is tied to economic growth; business, trade, and foreign direct investment are all based on effective sources of ICT, and development of ICT flourishes with a vigorous economy, open trade, and sound regulation; some 2020 estimates point to a digital economy worth $11.5 trillion globally, equivalent to 15.5% of global GDP (with ICT growing 2.5 times faster than global GDP over the past 15 years); 2020 reports indicate about 7.7 billion global mobile broadband subscriptions, rising from 3.3 billion in five years, and over 1.1 billion fixed broadband subscribers, up from 830 million in 2015

International: economic impact \- telecommunications has been and continues to be one of the world’s fastest growing markets; countries and firms are transitioning from analog to digital broadcasting, increasing automation capabilities and applications, adopting more high-definition technologies, and converting to digital channels

Broadcasting typically refers to transmission of information to all devices in a network without any acknowledgment by the receivers; data processing parts and accessories includes many supporting elements to broadcasting equipment, such as monitors, keyboards, printers, etc.

In terms of market size, broadcasting equipment constituted $413 billion in global trade, making it the fifth most traded commodity in 2019; similarly, data processing equipment equaled $230 billion, the eighth most traded commodity globally; the chief exporters and importers of telecommunications commodities remain largely the same: 1) China leads in both broadcasting and data processing equipment exports, $208 billion and $81.5 billion respectively and 2) the United States, conversely, receives the most of both commodities, importing $81.1 billion in broadcasting equipment and $38.3 billion in data processing equipment in 2019

Infrastructure \- as of 2021, 428 submarine cables have been laid worldwide with a further 36 planned; the undersea cables connect to 1,245 landing stations

Communications - note

Note 1: the development of formal postal systems may be traced back thousands of years; the earliest documented organized courier service for the dissemination of written dispatches was set up by the pharaohs of Ancient Egypt (ca. 2400 B.C.); the invention of a true postal system organized for delivery of post to citizens, is credited to Ancient Persia (6th century B.C.); other credible early postal services are those of Ancient India (Mauryan Empire; 4th century B.C.) and Ancient China (Han Dynasty; 3rd century B.C.)

Note 2: data centers consist of a dedicated space within a building or a group of buildings used to house computing resources and other components, such as telecommunications and storage systems; the ongoing worldwide boom in data generation is responsible for the mushrooming of data centers; the three largest data center facilities by area as of the first half of 2022 are:

No. 1. - the China Telecom data center located in the Inner Mongolia Information Park, Hohhot, China, reportedly covers 1 million sq m (10.7 million sq ft); the largest Internet data center in the World, it has over 50% market share in the Chinese data center market, with an extensive network of over 400 data centers located in prime regions in mainland China and overseas markets

No. 2. - the China Mobile data center located in the Inner Mongolia Information Park, Hohhot, China, covers 720,000 sq m (7.7 million sq ft); it is one of the World's biggest cloud computing data centers
