Most Populous Countries in the World

The 10 most populous countries in the world in 2024 are listed here. Learn the percentage, population density, and other details.

India: The Most Populous Nation

India now has more than 1.5 billion people, surpassing China as the world's most populous country. Its quick population growth is a result of its young median age and slightly above-replacement fertility rate. India's population is expected to make up about 18% of the world's by 2025.

China: A Historical Giant

China's population, which is at 1.5 billion, has grown considerably over the years, despite recent drops brought on by measures like the one-child policy (1980-2015). The country is currently dealing with issues brought on by a growing elderly population and falling birth rates.

United States: A Melting Pot

The United States is the third largest country in the world, with over 340 million people. Because of a lower fertility rate, immigration is the main factor driving its population growth rather than natural increases.

Indonesia and Pakistan: Rising Powers

The populations of Pakistan and Indonesia are around 240 million and 277 million, respectively. Both countries' young populations and high fertility rates are factors in their population growth.

Nigeria: Africa's Most Populous Country

Nigeria is the most populous country in Africa, with a population of about 224 million, and is expected to continue to grow due to its high fertility rate and development characteristics.

Brazil: South America's Largest Country

The estimated population of Brazil is 219 million, and while it has been growing slowly, it is expected to reach a peak of about 220 million by 2041 before reducing as a result of lowering fertility rates. Brazil's median age is 34, which means its population is younger than that of many rich countries.

Bangladesh: A Dense Population

About 173 million people live in Bangladesh, a densely populated country that presents problems with infrastructure and resources. It has grown significantly due in part to the fertility rate, which is about two children per woman.

Russia: Declining Numbers

Due to low birth rates and an aging population, Russia, which has 144 million people, is experiencing demographic issues. The need for programs that help younger families is shown by the relatively high median age of 40.

Mexico: A Growing Economy

Mexico, with a population of almost 128 million, completes the top 10. Its young median age of around thirty and two children per woman shows that it will continue to increase over the next several decades.

Key Factors Influencing Population Growth

What causes a country's population to grow or decline? It is necessary to understand these processes, particularly as the world's population continues to change and increase. Below is a summary of the main influences:
Key Factors Influencing Population Growth
Factor Impact on Population
Birth Rate Lower birth rates can cause a fall or delay population growth, whereas higher rates increase population growth.
Death Rate A low death rate may support population growth, whereas high death rates prevent it.
Migration Emigration decreases the population, while immigration increases it.
Fertility Rates More births and growth are the results of higher fertility rates, growth can be stopped or slowed by lower rates.
Mortality Rates Reduced mortality promotes population growth and is influenced by nutrition, sanitation, and healthcare.
Life Expectancy Because people live longer and remain in the population longer, increased life expectancy results in growth.
Economic Factors Population growth can be supported by economic stability and development, which may improve fertility rates and decrease mortality.
Social & Cultural Factors Fertility rates and population trends are influenced by norms and practices concerning marriage, family size, and contraception.
Government Policies Birth and mortality rates as well as migration trends are influenced by family planning, healthcare, and immigration policies.
Environmental Factors Living conditions and population movement are affected by climate change, natural disasters, and the availability of resources.
