  • Background field listing
    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, and 7 billion in 2012. 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 :: World
  • Geographic overview: Geographic overview field listing

    The surface of the earth is approximately 70.9% water and 29.1% land. The former portion is divided into large bodies termed oceans. The World Factbook recognizes and describes five oceans, which are in decreasing order of size: the Pacific Ocean, Atlantic Ocean, Indian Ocean, Southern Ocean, and Arctic Ocean. Because of their immense size, 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.

    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 14, and South America 12.

    Natural hazards field listing

    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"

    Geography - note field listing

    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

    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

  • Economy :: World
  • Economy - overview field listing

    The international financial crisis of 2008-09 led to the first downturn in global output since 1946 and presented the world with a major new challenge: determining what mix of fiscal and monetary policies to follow to restore growth and jobs, while keeping inflation and debt under control. Financial stabilization and stimulus programs that started in 2009-11, combined with lower tax revenues in 2009-10, required most countries to run large budget deficits. Treasuries issued new public debt - totaling $9.1 trillion since 2008 - to pay for the additional expenditures. To keep interest rates low, most central banks monetized that debt, injecting large sums of money into their economies - between December 2008 and December 2013 the global money supply increased by more than 35%. Governments are now faced with the difficult task of spurring current growth and employment without saddling their economies with so much debt that they sacrifice long-term growth and financial stability. When economic activity picks up, central banks will confront the difficult task of containing inflation without raising interest rates so high they snuff out further growth.

    Fiscal and monetary data for 2013 are currently available for 180 countries, which together account for 98.5% of world GDP. Of the 180 countries, 82 pursued unequivocally expansionary policies, boosting government spending while also expanding their money supply relatively rapidly - faster than the world average of 3.1%; 28 followed restrictive fiscal and monetary policies, reducing government spending and holding money growth to less than the 3.1% average; and the remaining 70 followed a mix of counterbalancing fiscal and monetary policies, either reducing government spending while accelerating money growth, or boosting spending while curtailing money growth.

    (For more information, see attached spreadsheet.)

    In 2013, for many countries the drive for fiscal austerity that began in 2011 abated. While 5 out of 6 countries slowed spending in 2012, only 1 in 2 countries slowed spending in 2013. About 1 in 3 countries actually lowered the level of their expenditures. The global growth rate for government expenditures increased from 1.6% in 2012 to 5.1% in 2013, after falling from a 10.1% growth rate in 2011. On the other hand, nearly 2 out of 3 central banks tightened monetary policy in 2013, decelerating the rate of growth of their money supply, compared with only 1 out of 3 in 2012. Roughly 1 of 4 central banks actually withdrew money from circulation, an increase from 1 out of 7 in 2012. Growth of the global money supply, as measured by the narrowly defined M1, slowed from 8.7% in 2009 and 10.4% in 2010 to 5.2% in 2011, 4.6% in 2012, and 3.1% in 2013. Several notable shifts occurred in 2013. By cutting government expenditures and expanding money supplies, the US and Canada moved against the trend in the rest of the world. France reversed course completely. Rather than reducing expenditures and money as it had in 2012, it expanded both. Germany reversed its fiscal policy, sharply expanding federal spending, while continuing to grow the money supply. South Korea shifted monetary policy into high gear, while maintaining a strongly expansionary fiscal policy. Japan, however, continued to pursue austere fiscal and monetary policies.

    Austere economic policies have significantly affected economic performance. The global budget deficit narrowed to roughly $2.7 trillion in 2012 and $2.1 trillion in 2013, or 3.8% and 2.5% of World GDP, respectively. But growth of the world economy slipped from 5.1% in 2010 and 3.7% in 2011, to just 3.1% in 2012, and 2.9% in 2013.

    Countries with expansionary fiscal and monetary policies achieved significantly higher rates of growth, higher growth of tax revenues, and greater success reducing the public debt burden than those countries that chose contractionary policies. In 2013, the 82 countries that followed a pro-growth approach achieved a median GDP growth rate of 4.7%, compared to 1.7% for the 28 countries with restrictive fiscal and monetary policies, a difference of 3 percentage points. Among the 82, China grew 7.7%, Philippines 6.8%, Malaysia 4.7%, Pakistan and Saudi Arabia 3.6%, Argentina 3.5%, South Korea 2.8%, and Russia 1.3%, while among the 28, Brazil grew 2.3%, Japan 2.0%, South Africa 2.0%, Netherlands -0.8%, Croatia -1.0%, Iran -1.5%, Portugal -1.8%, Greece -3.8%, and Cyprus -8.7%.

    Faster GDP growth and lower unemployment rates translated into increased tax revenues and a less cumbersome debt burden. Revenues for the 82 expansionary countries grew at a median rate of 10.7%, whereas tax revenues fell at a median rate of 6.8% for the 28 countries that chose austere economic policies. Budget balances improved for about three-quarters of the 28, but, for most, debt grew faster than GDP, and the median level of their public debt as a share of GDP increased 9.1 percentage points, to 59.2%. On the other hand, budget balances deteriorated for most of the 82 pro-growth countries, but GDP growth outpaced increases in debt, and the median level of public debt as a share of GDP increased just 1.9%, to 39.8%.

    The world recession has suppressed inflation rates - world inflation declined 1.0 percentage point in 2012 to about 4.1% and 0.2 percentage point to 3.9% in 2013. In 2013 the median inflation rate for the 82 pro-growth countries was 1.3 percentage points higher than that for the countries that followed more austere fiscal and monetary policies. Overall, the latter countries also improved their current account balances by shedding imports; as a result, current account balances deteriorated for most of the countries that pursued pro-growth policies. Slow growth of world income continued to hold import demand in check and crude oil prices fell. Consequently, the dollar value of world trade grew just 1.3% in 2013.

    Beyond the current global slowdown, the world faces several long standing economic challenges. The addition of 80 million people each year to an already overcrowded globe is exacerbating the problems of pollution, waste-disposal, epidemics, water-shortages, famine, over-fishing of oceans, deforestation, desertification, and depletion of non-renewable resources. The nation-state, as a bedrock economic-political institution, is steadily losing control over international flows of people, goods, services, funds, and technology. The introduction of the euro as the common currency of much of Western Europe in January 1999, while paving the way for an integrated economic powerhouse, has created economic risks because the participating nations have varying income levels and growth rates, and hence, require a different mix of monetary and fiscal policies. Governments, especially in Western Europe, face the difficult political problem of channeling resources away from welfare programs in order to increase investment and strengthen incentives to seek employment. Because of their own internal problems and priorities, the industrialized countries are unable to devote sufficient resources to deal effectively with the poorer areas of the world, which, at least from an economic point of view, are becoming further marginalized. The terrorist attacks on the US on 11 September 2001 accentuated a growing risk to global prosperity - the diversion of resources away from capital investments to counter-terrorism programs.

    Despite these vexing problems, the world economy also shows great promise. Technology has made possible further advances in a wide range of fields, from agriculture, to medicine, alternative energy, metallurgy, and transportation. Improved global communications have greatly reduced the costs of international trade, helping the world gain from the international division of labor, raise living standards, and reduce income disparities among nations. Much of the resilience of the world economy in the aftermath of the financial crisis resulted from government and central bank leaders around the globe working in concert to stem the financial onslaught, knowing well the lessons of past economic failures.

    note: rivers are not necessarily navigable along the entire length; if measured by volume, the Amazon is the largest river in the world, responsible for about 20% of the Earth's freshwater entering the ocean

    top ten largest natural lakes (by surface area): Caspian Sea (Azerbaijan, Iran, Kazakhstan, Russia, Turkmenistan) 372,960 sq km; Lake Superior (Canada, United States) 82,414 sq km; Lake Victoria (Kenya, Tanzania, Uganda) 69,490 sq km; Lake Huron (Canada, United States) 59,596 sq km; Lake Michigan (United States) 57,441 sq km; Lake Tanganyika (Burundi, Democratic Republic of the Congo, Tanzania, Zambia) 32,890 sq km; Great Bear Lake (Canada) 31,800 sq km; Lake Baikal (Russia) 31,494 sq km; Lake Nyasa (Malawi, Mozambique, Tanzania) 30,044 sq km; Great Slave Lake (Canada) 28,400 sq km

    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

    Maritime threats field listing

    The International Maritime Bureau (IMB) reports that 2018 saw an increase in global pirate activities; in 2018, pirates attacked a total of 201 ships worldwide including boarding 143 ships, hijacking six ships, and firing on 18; this activity is an increase from 180 incidents in 2017; in 2018, the number of hostages increased to 141, however, the number of seafarers kidnapped for ransom increased to 83 compared with 75 in 2017, with nearly all taken off West Africa

    Operation Ocean Shield, the NATO naval task force established in 2009 to combat Somali piracy, concluded its operations in December 2016 as a result of the drop in reported incidents over the last few years; the EU naval mission, Operation ATALANTA, continues its operations in the Gulf of Aden and Indian Ocean through 2020; naval units from Japan, India, and China also operate in conjunction with EU forces; China has established a logistical base in Djibouti to support its deployed naval units in the Horn of Africa

    The Horn of Africa continued to see pirate activities with three incidents in 2018, a slight decrease over 2017; the decrease in successful pirate attacks off the Horn of Africa since the peak in 2007 was due, in part, to anti-piracy operations by international naval forces, the hardening of vessels, and the increased use of armed security teams aboard merchant ships; despite these preventative measures, the assessed risk remains high

    West African piracy more than doubled in 2018 to become the most dangerous area in the world with 85 attacks in 2018 compared to 33 in 2017; Nigerian pirates are very aggressive, operating as far as 200 nm offshore and boarding 29 ships in 2018; attacks in South Asian waters remain at low levels with 12 attacks off Bangladesh in 2018, up from 11 in 2017; Peru reported four incidents in 2018, up from two in 2017; attacks in Vietnam rose from two in 2017 to four in 2018; the majority of global attacks against shipping have occurred in the offshore waters of five countries - Nigeria, Indonesia, Philippines, Venezuela, and Bangladesh.

  • Disputes - international field listing

    stretching over 250,000 km, the world's 325 international land boundaries separate 195 independent states and 71 dependencies, areas of special sovereignty, and other miscellaneous entities; ethnicity, culture, race, religion, and language have divided states into separate political entities as much as history, physical terrain, political fiat, or conquest, resulting in sometimes arbitrary and imposed boundaries; most maritime states have claimed limits that include territorial seas and exclusive economic zones; overlapping limits due to adjacent or opposite coasts create the potential for 430 bilateral maritime boundaries of which 209 have agreements that include contiguous and non-contiguous segments; boundary, borderland/resource, and territorial disputes vary in intensity from managed or dormant to violent or militarized; undemarcated, indefinite, porous, and unmanaged boundaries tend to encourage illegal cross-border activities, uncontrolled migration, and confrontation; territorial disputes may evolve from historical and/or cultural claims, or they may be brought on by resource competition; ethnic and cultural clashes continue to be responsible for much of the territorial fragmentation and internal displacement of the estimated 20.8 million people and cross-border displacements of approximately 12.1 million refugees and asylum seekers around the world as of mid-2013; over half a million refugees were repatriated during 2012; other sources of contention include access to water and mineral (especially hydrocarbon) resources, fisheries, and arable land; armed conflict prevails not so much between the uniformed armed forces of independent states as between stateless armed entities that detract from the sustenance and welfare of local populations, leaving the community of nations to cope with resultant refugees, hunger, disease, impoverishment, and environmental degradation

    Refugees and internally displaced persons field listing

    the UN High Commissioner for Refugees (UNHCR) estimated that as of year-end 2018 there were 70.8 million people forcibly displaced worldwide; this includes 25.9 million refugees, 3.5 million asylum seekers, and 41.4 million conflict IDPs; the UNHCR estimates there are currently at least 10 million stateless persons

    Trafficking in persons field listing
    current situation: the International Labour Organization conservatively estimated that 20.9 million people in 2012 were victims of forced labor, representing the full range of human trafficking (also referred to as 'modern-day slavery') for labor and sexual exploitation; about one-third of reported cases involved crossing international borders, which is often associated with sexual exploitation; trafficking in persons is most prevalent in southeastern Europe, Eurasia, and Africa and least frequent in EU member states, Canada, the US, and other developed countries (2012)
