Countries With the Largest Population in 2026 – India Leads as Ethiopia Enters the Top 10

India is the most populous country in the world in 2026, with an estimated 1.477 billion residents. China ranks second with 1.413 billion, followed by the United States with about 349 million.

The latest ranking looks different from lists published only a few years ago. India has established a clear lead over China. Ethiopia has entered the top 10, moving ahead of Mexico. Nigeria and Pakistan continue to add millions of residents each year, while China and Russia are losing population.

The world population is estimated at approximately 8.3 billion in 2026. India and China alone account for almost 35% of all people. The 10 largest countries contain more than 56% of the global population.

The 10 Most Populous Countries in 2026

The figures below use mid-year population estimates based on the latest United Nations population projections.

The ranking shows that population size and population growth are not the same thing. India is the largest country, but Nigeria and Ethiopia are growing much faster. China remains close to India in total size, but its population is declining.

The 2026 country population table also shows major differences in age, fertility, migration and urbanization across the top 10.

What Has Changed in the Global Population Ranking?

India now has about 63.7 million more people than China. That gap is expected to widen because India continues to grow, while China has entered a period of long-term population decline.

Ethiopia is the other major change near the top of the ranking. Its population has reached almost 139 million, placing it ahead of Mexico, which has about 133 million residents.

Mexico is still growing, but Ethiopia is adding people at a much faster rate. Ethiopia gained approximately 3.4 million residents in one year. Mexico added about 1.1 million.

Nigeria is also closing the distance on Pakistan. Nigeria added approximately 4.9 million people in a year, the largest increase among the 10 most populous countries.

1. India, 1.477 Billion

India accounts for 17.79% of the global population. More than one in every six people lives in the country.

Its population increased by approximately 12.8 million in one year. That growth does not mean Indian families are having unusually large numbers of children. India’s estimated fertility rate has fallen to 1.93 births per woman, slightly below the replacement level of approximately 2.1.

India continues to grow because it has a large and relatively young population. Millions of people are entering the ages when families are commonly formed, creating population momentum even as the average number of births per woman declines.

The country has a median age of about 29. Its large working-age population could support economic growth, but only when employment, housing, education, transportation and healthcare expand at a similar pace.

2. China, 1.413 Billion

China remains home to 17.02% of the world population, but its demographic direction has changed.

The country lost an estimated 3.2 million residents in one year. Its fertility rate is approximately 1.03 births per woman, one of the lowest rates among large countries.

China also has a rapidly aging population. The median age is above 40, and the number of people entering retirement is increasing as the working-age population contracts.

Government support for larger families has not produced a major birth-rate recovery. High housing costs, childcare expenses, education costs and changing attitudes toward marriage have all influenced family size.

The consequences extend beyond population totals. A smaller workforce can place more pressure on pension systems, healthcare services and employers seeking skilled workers.

3. United States, 349 Million

The United States remains the third-most populous country, but it has less than one-quarter of China’s population and less than one-quarter of India’s.

Population growth is increasingly connected to immigration. The country recorded net migration of approximately 1.18 million people in the 2026 estimate.

The natural increase from births exceeding deaths has weakened as the population ages and fertility remains below replacement level.

The United States has a low population density of 38 people per square kilometer. The national average hides major differences between heavily populated metropolitan corridors and vast rural regions.

Immigration policy will have a growing influence on future population size, labor supply and the pace of population aging.

4. Indonesia, 287.9 Million

Indonesia is the largest country in Southeast Asia by population and the fourth largest in the world.

Its residents are spread across thousands of islands, although a large share of the population remains concentrated on Java. The uneven distribution creates major differences in housing pressure, infrastructure and access to public services.

Indonesia is becoming more urban. Approximately 60% of its residents now live in urban areas.

The country has also been developing Nusantara as a new capital, partly to reduce the concentration of government activity in Jakarta. Moving administrative functions will not immediately change Jakarta’s importance as Indonesia’s largest economic and urban center.

5. Pakistan, 259.3 Million

Pakistan added approximately 4.1 million residents in a year. Its population is growing at 1.6% annually.

The median age is about 21, making Pakistan much younger than China, the United States, Brazil and Russia.

A young population can expand the workforce and consumer market. It also creates immediate demand for schools, universities, housing, healthcare and employment.

Pakistan remains less urbanized than several other large countries, with about 35% of its population living in urban areas. Karachi and Lahore continue to expand rapidly as people move in search of jobs and services.

6. Nigeria, 242.4 Million

Nigeria is Africa’s most populous country and the fastest-growing member of the top six.

Its population increased by approximately 4.9 million in a year. The median age is just over 18, and the fertility rate remains above four births per woman.

Nigeria could move past Pakistan in the global ranking if current growth differences continue. Longer-term UN projections also place Nigeria among the countries expected to contribute the largest shares of future world population growth.

Population size creates a large domestic market and a growing labor force. The economic benefit depends on job creation, education, electricity supply, housing and transportation keeping pace.

7. Brazil, 213.6 Million

Brazil remains the largest country in South America by population, but its growth has slowed to 0.35% per year.

Its fertility rate has fallen to approximately 1.59 births per woman. Brazil is therefore moving toward an older and more slowly growing population.

More than 91% of Brazilians live in urban areas, one of the highest urban shares among the top 10 countries.

Population is heavily concentrated in cities and coastal regions. Large parts of the interior have low population density despite Brazil’s enormous land area.

8. Bangladesh, 177.8 Million

Bangladesh has the highest population density among the 10 largest countries. Approximately 1,366 people live on each square kilometer of land.

The country has almost 178 million people living on about 130,000 square kilometers of land. That combination creates intense pressure on housing, transportation, farmland and public infrastructure.

Bangladesh continues to grow, but fertility has fallen close to replacement level. The median age is approximately 26.

Dhaka is one of the clearest examples of the country’s rapid urban change. The latest standardized UN calculation ranks it as the second-largest city in the world.

9. Russia, 143.4 Million

Russia is the largest country in the world by land area but has only nine residents per square kilometer.

Its population is highly concentrated in the western part of the country and in major urban centers. Vast northern and eastern territories remain sparsely populated.

Russia’s population declined by approximately 603,000 in one year. Low fertility, an aging population, mortality and migration all influence the long-term trend.

The median age is above 40. A shrinking working-age population can create labor shortages and increase pressure on social programs.

10. Ethiopia, 138.9 Million

Ethiopia is now the 10th-most populous country, passing Mexico in the global ranking.

The country is adding approximately 3.4 million residents per year and has a growth rate of 2.53%. Its median age is about 19.

Only around 23% of Ethiopians live in urban areas. The national population is still predominantly rural, although cities are expanding rapidly.

The scale of future growth will increase demand for food, jobs, housing, water, electricity, schools and medical care. It will also increase Ethiopia’s economic and political importance in Africa.

The Fastest-Growing and Shrinking Countries in the Top 10

India adds the most residents in absolute numbers because even modest percentage growth produces a large increase when applied to a population of almost 1.5 billion.

Ethiopia has the fastest percentage increase in the top 10. Nigeria follows. China records the largest numeric loss, while Russia has the sharper percentage decline.

Population Growth Is Becoming More Concentrated

Global population is still increasing, but the growth is no longer evenly distributed.

Many countries in Europe and East Asia have already reached their population peaks. China, Japan, Russia, Italy, South Korea and several other countries are declining or expected to decline.

Much of the growth through the middle of the century will come from countries in sub-Saharan Africa and South Asia. Nigeria, Ethiopia, the Democratic Republic of the Congo, Tanzania and Pakistan will account for a growing share of new residents.

The United Nations expects the world population to peak at approximately 10.3 billion during the mid-2080s before declining slightly by the end of the century.

Population growth is slowing because fertility has fallen in most regions. The global population can continue increasing for decades because of population momentum and longer life expectancy.

The 10 Least Populated Sovereign Countries in 2026

Lists of the world’s smallest populations often mix sovereign countries with dependent territories. Montserrat, Anguilla and Saint Pierre and Miquelon have very small populations, but they are not independent sovereign states.

The table below includes sovereign states only. A wider comparison of population and land size is available in our guide to the smallest countries in the world.

Small population does not mean limited international importance. The Holy See has worldwide religious influence. Monaco and Liechtenstein have significant financial sectors. Palau, Tuvalu and the Marshall Islands play prominent roles in climate diplomacy and marine conservation.

Several small island states are losing residents through emigration. The Marshall Islands declined by more than 3% in one year, while Tuvalu also recorded a population decrease.

Population Density Changes the Meaning of Size

Two countries can have similar populations and completely different settlement patterns.

Bangladesh has about 178 million residents and a density of 1,366 people per square kilometer. Russia has 143 million residents and a density of nine people per square kilometer.

India is more than three times as dense as China. The United States has a larger population than Indonesia but a far lower national density.

National density also hides internal differences. Most Canadians live near the southern border. Russia’s population is concentrated in the west. Brazil’s largest cities are located mainly near the Atlantic coast.

Environmental pressure depends on consumption, energy systems, industrial activity and policy as well as population. A large population does not automatically make a country one of the world’s most polluted countries.

Population Size Does Not Determine Economic Power

A large population can provide a broad workforce, domestic consumer market and tax base. It can also create enormous pressure on housing, education, infrastructure and employment.

The United States has less than one-quarter of India’s population but a much larger economy. Germany, the United Kingdom, France and Italy remain major economic powers with fewer than 100 million residents each.

Small countries can also have a large economic role. Luxembourg, Singapore, Switzerland, Monaco and Liechtenstein have populations far below those of the largest countries but hold important positions in finance, trade and investment.

Population size is therefore one factor among many. Productivity, education, institutions, natural resources, technology, trade and political stability also influence economic strength.

Our ranking of the largest economies in the world shows how economic influence can differ sharply from population rank.

The Largest Cities in the World

City rankings depend heavily on how boundaries are drawn. An administrative city may cover only the urban core, while a metropolitan area can include dozens of surrounding municipalities.

The latest United Nations urban population dataset applies a more consistent global method based on population density and built-up areas.

Under that method, Jakarta ranks first with nearly 42 million residents. Dhaka is second, and Tokyo has moved to third.

Nine of the 10 largest cities are in Asia. Cairo is the only city from another continent.

The new methodology is also the main reason Jakarta appears above Tokyo. It does not mean that Jakarta suddenly gained millions of residents in a single year. The standardized boundaries capture the full connected urban settlement differently from older rankings.

There are now 33 megacities with at least 10 million residents. The total is expected to reach 37 by 2050.

How Births, Deaths and Migration Change Population

Population changes through three basic components:

• births
• deaths
• international migration

When births exceed deaths, a country records natural population growth. When deaths exceed births, migration may still prevent the total population from declining.

The United States provides a clear example. Its fertility rate is below replacement level, but positive net migration supports continued growth.

China shows the opposite pattern. Low fertility, population aging and a limited contribution from immigration have pushed the population into decline.

Countries such as Nigeria and Ethiopia combine young age structures with higher fertility. They therefore record large natural increases even when net migration is negative.

Methodology

Country population totals, annual changes, densities and world shares use mid-year estimates derived from the latest United Nations World Population Prospects medium projection.

The ranking covers sovereign countries. Dependent territories are excluded from the list of the least populated countries.

City populations use the latest United Nations World Urbanization Prospects dataset. Its standardized degree-of-urbanization method produces different results from rankings based on administrative boundaries or older metropolitan definitions.

Population figures are estimates rather than live headcounts. They may be revised as national censuses, birth records, death registrations, migration estimates and survey results become available.

Final Thoughts

The world’s population is not growing in one uniform direction. India is expanding more slowly than before but still adds almost 13 million residents in a year. China has begun a long decline. Nigeria and Ethiopia are growing rapidly, while Russia is shrinking.

The top of the ranking also shows a broader shift. Future population growth will be increasingly concentrated in Africa and South Asia. Countries in Europe and East Asia will face older populations and smaller workforces.

Population size can create economic potential, but it does not guarantee prosperity. The result depends on jobs, education, housing, healthcare, infrastructure and the ability of governments to manage demographic change.
