Russia is the largest country in the world by far, with a total area of just over 17 million square kilometers. After Antarctica, the next three countries are Canada, the U.S., and China; all between 9.5 and 10 million square kilometers. The figures given include internal water surface area (such as lakes or rivers) - if the figures were for land surface only then China would be the second largest country in the world, the U.S. third, and Canada (the country with more lakes than the rest of the world combined) fourth. Russia Russia has a population of around 145 million people, putting it in the top ten most populous countries in the world, and making it the most populous in Europe. However, it's vast size gives it a very low population density, ranked among the bottom 20 countries. Most of Russia's population is concentrated in the west, with around 75 percent of the population living in the European part, while around 75 percent of Russia's territory is in Asia; the Ural Mountains are considered the continental border. Elsewhere in the world Beyond Russia, the world's largest countries all have distinctive topographies and climates setting them apart. The United States, for example, has climates ranging from tundra in Alaska to tropical forests in Florida, with various mountain ranges, deserts, plains, and forests in between. Populations in these countries are often concentrated in urban areas, and are not evenly distributed across the country. For example, around 85 percent of Canada's population lives within 100 miles of the U.S. border; around 95 percent of China lives east of the Heihe–Tengchong Line that splits the country; and the majority of populations in large countries such as Australia or Brazil live near the coast.

In 2025, India overtook China as the world's most populous country and now has almost 1.46 billion people. China now has the second-largest population in the world, still with just over 1.4 billion inhabitants, however, its population went into decline in 2023. Global population As of 2025, the world's population stands at almost 8.2 billion people and is expected to reach around 10.3 billion people in the 2080s, when it will then go into decline. Due to improved healthcare, sanitation, and general living conditions, the global population continues to increase; mortality rates (particularly among infants and children) are decreasing and the median age of the world population has steadily increased for decades. As for the average life expectancy in industrial and developing countries, the gap has narrowed significantly since the mid-20th century. Asia is the most populous continent on Earth; 11 of the 20 largest countries are located there. It leads the ranking of the global population by continent by far, reporting four times as many inhabitants as Africa. The Demographic Transition The population explosion over the past two centuries is part of a phenomenon known as the demographic transition. Simply put, this transition results from a drastic reduction in mortality, which then leads to a reduction in fertility, and increase in life expectancy; this interim period where death rates are low and birth rates are high is where this population explosion occurs, and population growth can remain high as the population ages. In today's most-developed countries, the transition generally began with industrialization in the 1800s, and growth has now stabilized as birth and mortality rates have re-balanced. Across less-developed countries, the stage of this transition varies; for example, China is at a later stage than India, which accounts for the change in which country is more populous - understanding the demographic transition can help understand the reason why China's population is now going into decline. The least-developed region is Sub-Saharan Africa, where fertility rates remain close to pre-industrial levels in some countries. As these countries transition, they will undergo significant rates of population growth.

As of May 2025, China had the largest armed forces in the world by active duty military personnel, with about *********** active soldiers. India, the United States, North Korea, and Russia rounded out the top five largest armies. Difference between active and reserve personnel Active personnel, also known as active duty in the United States and active service in the United Kingdom, are those individuals whose full-time occupation is being part of a military force. Active duty contrasts with a military’s reserve force, which are individuals who have both a military role and a civilian career. The number of active duty forces in the U.S. is much larger than its reserve membership. What is the strongest army? The strength of a country’s armed forces is not only determined by how many personnel they maintain, but also the number and quality of their military equipment. For example, looking only at personnel does not factor in the overwhelmingly higher number of nuclear warheads owned by Russia and the United States compared to other countries. One way to answer this question is to look at the total amount of money each country spends on their military, as spending includes both personnel and technology. In terms of countries with the highest military spending, the United States leads the world with an annual budget almost ***** times larger than second-placed China.

Context The current US Census Bureau world population estimate in June 2019 shows that the current global population is 7,577,130,400 people on earth, which far exceeds the world population of 7.2 billion in 2015. Our own estimate based on UN data shows the world's population surpassing 7.7 billion.

China is the most populous country in the world with a population exceeding 1.4 billion. It is one of just two countries with a population of more than 1 billion, with India being the second. As of 2018, India has a population of over 1.355 billion people, and its population growth is expected to continue through at least 2050. By the year 2030, the country of India is expected to become the most populous country in the world. This is because India’s population will grow, while China is projected to see a loss in population.

The following 11 countries that are the most populous in the world each have populations exceeding 100 million. These include the United States, Indonesia, Brazil, Pakistan, Nigeria, Bangladesh, Russia, Mexico, Japan, Ethiopia, and the Philippines. Of these nations, all are expected to continue to grow except Russia and Japan, which will see their populations drop by 2030 before falling again significantly by 2050.

Many other nations have populations of at least one million, while there are also countries that have just thousands. The smallest population in the world can be found in Vatican City, where only 801 people reside.

In 2018, the world’s population growth rate was 1.12%. Every five years since the 1970s, the population growth rate has continued to fall. The world’s population is expected to continue to grow larger but at a much slower pace. By 2030, the population will exceed 8 billion. In 2040, this number will grow to more than 9 billion. In 2055, the number will rise to over 10 billion, and another billion people won’t be added until near the end of the century. The current annual population growth estimates from the United Nations are in the millions - estimating that over 80 million new lives are added each year.

This population growth will be significantly impacted by nine specific countries which are situated to contribute to the population growing more quickly than other nations. These nations include the Democratic Republic of the Congo, Ethiopia, India, Indonesia, Nigeria, Pakistan, Uganda, the United Republic of Tanzania, and the United States of America. Particularly of interest, India is on track to overtake China's position as the most populous country by 2030. Additionally, multiple nations within Africa are expected to double their populations before fertility rates begin to slow entirely.

In 2021, the BRICS countries with the highest estimated GDP per capita were Russia and China, with between 12,000 and 13,000 U.S. dollars per person. Brazil and South Africa's GDP per capita are thought to be closer to the 7,000 mark, while India's GDP per capita is just over 2,000 U.S. dollars. This a significant contrast to figures for overall GDP, where China has the largest economy by a significant margin, while India's is the second largest. The reason for this disparity is due to population size. For example, both China's population and overall GDP are roughly 10 times larger than those of Russia, which results in them having a comparable GDP per capita. Additionally, India's population is 23 times larger than South Africa's, but it's GDP is just seven times larger; this results in South Africa having a higher GDP per capita than India, despite it being the smallest of the BRICS economies.

Since the beginning of the 21st century, the BRICS countries have been considered the five foremost developing economies in the world. Originally, the term BRIC was used by economists when talking about the emerging economies of Brazil, Russia, India, and China, however these countries have held annual summits since 2009, and the group has expanded to include South Africa since 2010. China has the largest GDP of the BRICS country, at 16.86 trillion U.S. dollars in 2021, while the others are all below three trillion. Combined, the BRICS bloc has a GDP over 25.85 trillion U.S. dollars in 2022, which is slightly more than the United States. BRICS economic development China has consistently been the largest economy of this bloc, and its rapid growth has seen it become the second largest economy in the world, behind the U.S.. China's growth has also been much faster than the other BRICS countries; for example, when compared with the second largest BRICS economy, its GDP was less than double the size of Brazil's in 2000, but is almost six times larger than India's in 2021. Since 2000, the country with the second largest GDP has fluctuated between Brazil, Russia, and India, due to a variety of factors, although India has held this position since 2015 (when the other two experienced recession), and it's growth rate is on track to surpass China's in the coming decade. South Africa has consistently had the smallest economy of the BRICS bloc, and it has just the third largest economy in Africa; its inclusion in this group is due to the fact that it is the most advanced and stable major economy in Africa, and it holds strategic importance due to the financial potential of the continent in the coming decades. Future developments It is predicted that China's GDP will overtake that of the U.S. by the end of the 2020s, to become the largest economy in the world, while some also estimate that India will also overtake the U.S. around the middle of the century. Additionally, the BRICS group is more than just an economic or trading bloc, and its New Development Bank was established in 2014 to invest in sustainable infrastructure and renewable energy across the globe. While relations between its members were often strained or of less significance in the 20th century, their current initiatives have given them a much greater international influence. The traditional great powers represented in the Group of Seven (G7) have seen their international power wane in recent decades, while BRICS countries have seen theirs grow, especially on a regional level. Today, the original BRIC countries combine with the Group of Seven (G7), to make up 11 of the world's 12 largest economies, but it is predicted that they will move further up on this list in the coming decades.

Russia was the largest country in the Commonwealth of Independent States (CIS) region, with a total area of over 17 million square kilometers in 2025. Furthermore, Russia was the largest country in the world, followed by Canada, the United States, and China. Ranking second among the CIS countries was Kazakhstan, whose land area comprised about 2.7 million square kilometers.

In 2023, it is estimated that the BRICS countries have a combined population of 3.25 billion people, which is over 40 percent of the world population. The majority of these people live in either China or India, which have a population of more than 1.4 billion people each, while the other three countries have a combined population of just under 420 million. Comparisons Although the BRICS countries are considered the five foremost emerging economies, they are all at various stages of the demographic transition and have different levels of population development. For all of modern history, China has had the world's largest population, but rapidly dropping fertility and birth rates in recent decades mean that its population growth has slowed. In contrast, India's population growth remains much higher, and it is expected to overtake China in the next few years to become the world's most populous country. The fastest growing population in the BRICS bloc, however, is that of South Africa, which is at the earliest stage of demographic development. Russia, is the only BRICS country whose population is currently in decline, and it has been experiencing a consistent natural decline for most of the past three decades. Growing populations = growing opportunities Between 2000 and 2026, the populations of the BRICS countries is expected to grow by 625 million people, and the majority of this will be in India and China. As the economies of these two countries grow, so too do living standards and disposable income; this has resulted in the world's two most populous countries emerging as two of the most profitable markets in the world. China, sometimes called the "world's factory" has seen a rapid growth in its middle class, increased potential of its low-tier market, and its manufacturing sector is now transitioning to the production of more technologically advanced and high-end goods to meet its domestic demand.

In 2024, the gross domestic product (GDP) of China amounted to around 18.7 trillion U.S. dollars. In comparison to the GDP of the other BRIC countries India, Russia and Brazil, China came first that year and second in the world GDP ranking. The stagnation of China's GDP in U.S. dollar terms in 2022 and 2023 was mainly due to the appreciation of the U.S. dollar. China's real GDP growth was 5.4 percent in 2023 and 5.0 percent in 2024. In 2024, per capita GDP in China reached around 13,300 U.S. dollars. Economic performance in China Gross domestic product (GDP) is a primary economic indicator. It measures the total value of all goods and services produced in an economy over a certain time period. China's economy used to grow quickly in the past, but the growth rate of China’s real GDP gradually slowed down in recent years, and year-on-year GDP growth is forecasted to range at only around four percent in the years after 2024. Since 2010, China has been the world’s second-largest economy, surpassing Japan.China’s emergence in the world’s economy has a lot to do with its status as the ‘world’s factory’. Since 2013, China is the largest export country in the world. Some argue that it is partly due to the undervalued Chinese currency. The Big Mac Index, a simplified and informal way to measure the purchasing power parity between different currencies, indicates that the Chinese currency yuan was roughly undervalued by 38 percent in 2024. GDP development Although the impressive economic development in China has led millions of people out of poverty, China is still not in the league of industrialized countries on the per capita basis. To name one example, the U.S. per capita economic output was more than six times as large as in China in 2024. Meanwhile, the Chinese society faces increased income disparities. The Gini coefficient of China, a widely used indicator of economic inequality, has been larger than 0.45 over the last decade, whereas 0.40 is the warning level for social unrest.

The United States led the ranking of the countries with the highest military spending in 2024, with 997 billion U.S. dollars dedicated to the military. That constituted almost 40 percent of the total military spending worldwide that year, which amounted to 2.7 trillion U.S. dollars. This amounted to 3.4 percent of the U.S.'s gross domestic product (GDP), placing the country lower in the ranking of military expenditure as a percentage of GDP, compared to Ukraine, Israel, Algeria, Saudi Arabia, and Russia. China was the second largest military spender, with an estimated 314 billion U.S. dollars spent, with Russia following in third. Defense budgetAccording to the U.S. Congressional Budget Office, the outlays for defense will rise to 1.1 trillion U.S. dollars by 2033. The largest parts of the budget are dedicated to the Departments of the Navy and the Air Force. The budget for the U.S. Air Force for 2024 was nearly 260 billion U.S. dollars.Global military spendingThe value of military spending globally has grown steadily in the past years and reached 2.7 trillion U.S. dollars in 2024. Reasons for this are the outbreak of the Russia-Ukraine war in 2022, the war in Gaza, as well as increasing tensions in the South China Sea. North America is by far the leading region worldwide in terms of expenditure on the military.

In 2025, the United States had the largest economy in the world, with a gross domestic product of over 30 trillion U.S. dollars. China had the second largest economy, at around 19.23 trillion U.S. dollars. Recent adjustments in the list have seen Germany's economy overtake Japan's to become the third-largest in the world in 2023, while Brazil's economy moved ahead of Russia's in 2024. Global gross domestic product Global gross domestic product amounts to almost 110 trillion U.S. dollars, with the United States making up more than one-quarter of this figure alone. The 12 largest economies in the world include all Group of Seven (G7) economies, as well as the four largest BRICS economies. The U.S. has consistently had the world's largest economy since the interwar period, and while previous reports estimated it would be overtaken by China in the 2020s, more recent projections estimate the U.S. economy will remain the largest by a considerable margin going into the 2030s.The gross domestic product of a country is calculated by taking spending and trade into account, to show how much the country can produce in a certain amount of time, usually per year. It represents the value of all goods and services produced during that year. Those countries considered to have emerging or developing economies account for almost 60 percent of global gross domestic product, while advanced economies make up over 40 percent.

As of April 2025, China was home to the largest number of pigs of any country with over 427 million heads. That year, the European Union and United States were second and third in the list, with over 132 and 76 million heads respectively. Global overview There were about 778.64 million pigs worldwide as of April 2022, meaning that China was home to more than half of the global pig population. Unsurprisingly, China is the leading pork producer worldwide, producing about 50 million metric tons of pork each year. China’s global pork exports have been decreasing over the past few years, while the EU remained the top exporter with about 3.75 million metric tons of pork shipments in the most recent year. The United States is also among the main exporters and importers of pork worldwide. Mexico was the main importer of U.S. pork, followed by Japan, China and Hong Kong, and South Korea.

Since 2000, China has consistently been the largest importer of goods of the BRICS countries, with a value of more than ************ U.S. dollars in 2020. China's value of imported goods has grown significantly across these two decades; values in 2018 were over **** times larger than values for 2000. India's imports in 2018 were also ** times higher in 2018 than in 2000. For Russia and Brazil, however, their peak years came in the early-2010s, just before both countries went into recession. South Africa's value of imported goods has also increased, and was over *** billion U.S. dollars in most years of the 2010s. In 2000, the value of goods imported to China was comparable to the other four BRICS countries combined; in 2022, the value was more than double the other countries combined.

China is the largest consumer of primary energy in the world, having used some 176.35 exajoules in 2024. This is a lot more than what the United States consumed, which comes in second place. The majority of primary energy fuels worldwide are still derived from fossil fuels, such as oil and coal. China's energy mix China’s primary energy mix has shifted from a dominant use of coal to an increase in natural gas and renewable sources. Since 2013, the renewables share in total energy consumption has grown by around eight percentage points. Overall, global primary energy consumption has increased over the last decade, and it is expected to experience the largest growth in emerging economies like the BRIC countries - Brazil, Russia, India, and China. What is primary energy? Primary energy is the energy inherent in natural resources such as crude oil, coal, and wind before further transformation. For example, crude oil can be refined into secondary fuels, such as gasoline or diesel, while wind is harnessed for electricity - itself a secondary energy source. A country’s total primary energy supply is a measure of the country’s primary energy sources. Meanwhile, end-use energy is the energy directly consumed by the user and includes primary fuels such as natural gas, as well as secondary sources, like electricity and gasoline.

China has the greatest number of coal-fired power stations of any country or territory in the world. As of July 2025, there were 1,195 operational coal power plants on the Chinese Mainland. This was more than four times the number of such power stations in India, which ranked second. China accounts for over 50 percent of total global coal electricity generation. Coal phase-out worldwide Coal power plants present various health and environmental threats. Besides demanding large quantities of raw material to be burned, this energy source pollutes water and has high greenhouse gas emissions. Due to these reasons and to tackle the climate crisis, 40 countries committed to phase out their coal power plants at the COP26 summit in 2021. However, the three leading economies with the greatest number of operational coal-fired plants that year did not agree to the terms. In 2024, the global capacity of coal power plants in construction stood at 227.5 gigawatts with an additional 111.5 gigawatts announced. Carbon dioxide emissions China has been the largest coal polluter worldwide since 1990. In 2023, figures reached a record high of 8.55 billion metric tons of carbon dioxide. That year, India had the second largest carbon dioxide emissions from coal use, followed by the United States. The U.S. was either the largest or second-largest polluter for 55 years, before being overtaken by India.

As a share of gross domestic product (GDP), Ukraine spent more on its military than any other country in 2024, reaching 35 percent of the country's GDP. The high figure is due to the country being invaded by Russia in February 2022. Israel, that is fighting Hamas in the Gaza war, and Algeria followed behind.Leading military spending countriesIn gross terms, the countries with the highest military spending are the United States, China, and Russia. However, these are countries with large populations and GDPs, and smaller countries usually cannot compete alone, regardless of how much they invest. For this reason, they form alliances such as the North Atlantic Treaty Organization (NATO). NATO countries aim to pool two percent of their GDP towards their own militaries and to aid each other in case of war. Regional differencesThe past decade has seen an increase in global military spending. This has not been distributed evenly. That period saw large positive changes in military spending from several Asian countries, including a large increase from China. While this does not reflect the number of active conflicts, it reflects growing tensions in global affairs.

The international land border between the United States and Canada is the longest in the world at almost 8,900 kilometers. It includes the border between Canada and the continental U.S. as well as the border between Alaska and northern Canada.

At the beginning of 2025, the United States had the highest number of incarcerated individuals worldwide, with around 1.8 million people in prison. China followed with around 100,000 fewer prisoners. Brazil followed in third. The incarceration problem in the U.S. The United States has an incredibly high number of incarcerated individuals. Therefore, the incarceration problem has become a widely contested issue, because it impacts disadvantaged people and minorities the most. Additionally, the prison system has become capitalized by outside corporations that fund prisons, but there is still a high cost to taxpayers. Furthermore, there has been an increase in the amount of private prisons that have been created. For-profit prison companies have come under scrutiny because of their lack of satisfactory staff and widespread lobbying. Violent offenses are the most common type of offense among prisoners in the U.S. Incarceration rates worldwide El Salvador had the highest rate of incarceration worldwide, at 1,659 prisoners per 100,000 residents as of February 2025. Cuba followed in second with 794 prisoners per 100,000 inhabitants. The incarceration rate is a better measure to use when comparing countries than the total prison populations, which will naturally have the most populous countries topping the list.

The export trade of the European Union experienced some notable shifts over the two decades since 2002, with China emerging as a significant export market and the United Kingdom losing its place as the EU's single largest export partner. The United Kingdom's declining share of EU exports The UK, which was a member of the European Union until 2020, declined in its importance as an export market for EU producers over this period. Representing over a fifth of the export trade in 2002, the UK now takes only 13 percent of EU exports, and looks likely to be eclipsed by China's growing share in the coming years. The complications to EU-UK trade caused by the UK's exit agreement with the EU is also likely to contribute to slowing trade flows between the two partners. China's emergence as a key export market As with most other areas of the global economy, the past two decades has largely been the story of China's emergence as a key trading partner. China's share of EU exports was comparable to Japan or Norway at the beginning of the period, while it now represents the EU's third largest export market. While this is a significant change, China takes up a much larger share of imports into the EU, where it is the largest single trading partner. As Chinese incomes rise in the coming decades, the significance of China as an export market for EU producers is likely to rise, geopolitical tension notwithstanding. The Euro and exports to the U.S. The EU's export trade with the United States over this period experienced a relative decline in the period running up to 2014, as the Euro appreciated in its value against the U.S. dollar, making European exports more expensive for Americans. This declining share of the EU's export trade taken by the U.S. was reversed in the latter half of the 2010s however, as the Euro depreciated and European exports to the U.S. increased. Issues with Russia Another notable trend over the period was Russia's emergence as a key export market in the mid-2000s, as the Russian economy grew quickly and Russian consumers began to demand EU made products. Russia declined as a market for EU exports after 2014, as trade was complicated by Russia's illegal annexation of Crimea from Ukraine, and the subsequent devaluation of the Ruble and collapse in the price of Ural crude oil.
