Explore the Most Populated Countries Here

The world is brimming with life, and the human population has been on a steady rise for centuries now. According to UNFPA, the estimates show that the planet has surpassed 8 billion people as of 2023. This remarkable growth is, however, not uniform across the globe. While there are countries that barely contribute to a fraction of the total population, these 7 countries contribute to more than half of the world’s population. This blog will explore the list of the most populated countries.

Most Populated Countries in the World

It took thousands of years for the world population to grow to 1 billion, and then in just another 200 years or so, it grew sevenfold. In 2011, the population of countries reached the 7 billion mark, and in November 2022, it reached 8 billion, as per the UN.

This dramatic growth has been driven largely by increasing numbers of people surviving to reproductive age and has been accompanied by major changes in fertility rates, increasing urbanisation, and large-scale migration. 

7 Most Populated Countries in the World

The United Nations estimates that the Asian population by 2055, will reach 5.3 billion. Latin America will reach its population peals at 752 million inhabitants. African and North American populations are expected to keep growing, albeit at a slower pace, while the European populations are already declining.

This blog explores the list of most populated countries in the world, their location, sizes, and distinctive characteristics:


India, located in Southeast Asia, is the most populous country globally. As of 2023, its population surged, marking a notable increase from the previous year’s count, representing a growth rate of 0.81%. 

The dynamics of the Indian population are shaped by many factors, including historical, cultural, economic, and policy-related influences. Rapid urbanisation, improvements in healthcare, and sociocultural norms surrounding family size, and gender roles all contribute to our country’s demographic trends.

  • Population: 1,428,627,663,000  
  • Size: 3.3M km2
  • Location: South Asia


China, situated in East Asia, is 2nd on the list of most populated countries. As of 2023, China’s population experienced a slight decrease from 2022 to 2023, reflecting a decline rate of 0.02%.

One notable aspect of China’s demographic profile is its low fertility rate, which stands at 1.19. This figure indicates that, on average, each woman bears approximately 1 child during her reproductive years. This fertility rate is notably low, posing challenges related to an ageing population and labour force dynamics.

  • Population: 1,425,671,352,000 
  • Size: 9.7M km2
  • Location: East Asia

United States of America 

The USA holds a significant position as the third most populous country in the world. The USA is also one of the most popular countries in the world. As of 2023, the population of the USA surged, reflecting a growth rate of 0.50%, a testament to the country’s dynamic population landscape.

Despite the USA’s expansive territory, the population density there is relatively moderate, with an average of 37 persons per square kilometre.

  • Population: 339,996,563,000
  • Size: 9.4M km2
  • Location: North America


Known for its diverse tourist attractions, Indonesia is 4th on the list of most populated countries globally. As of 2023, the population of Indonesia surged, reflecting a growth rate of 0.74%. Despite Indonesia’s vast territory, the population density there is relatively moderate, with an average of 153 persons per square kilometre.

  • Population: 277,534,122,000
  • Size: 1.9M km2
  • Location: Asia


Pakistan is the 5th most populous country in the world. As of 2023, the population of Pakistan surged, representing a growth rate of 1.98%. Despite its relatively small size, Pakistan encompasses diverse landscapes from fertile plains to rugged mountain ranges and has a relatively high population density, with an average of 312 persons per km2

  • Population: 240,485,658,000
  • Size: 881.9K km2
  • Location: South Asia


Nigeria is 6th on the list of most populated countries globally. The country has a high population growth rate of 2.4%, which is sustained by high fertility. The growth here was fastest in the 1980s after child mortality dropped rapidly.

  • Population: 223,804,632,000
  • Size: 923.8K km2
  • Location: West Africa


Well known for its dense forests, including the Amazon, Brazil is 7th on the list of most populated countries in the world. Brazil’s population has been rapidly growing since the 1960s; immigrants from both Europe and Africa have been coming to the country in droves due to its growing economic and cultural diversity. 

  • Population: 216,422,446,000
  • Size: 8.5M km2
  • Location: South America

Global Significance of Most Populous Countries

Countries with high population densities often have large economies and make major contributions to international trade and commerce. The most populous countries can have a significant impact on global culture. These countries can also exert greater influence on international affairs and can create a pool of talented and innovative people, leading to advancements in science and technology.

Future of Most Populated Countries

The world population growth over the past two centuries is largely the result of progress in modern medicine and reductions in global poverty. These have significantly reduced infant mortality, child mortality, and maternal mortality, contributing to an increase in life expectancy.

Although fertility levels have fallen, they have not fallen at the same pace as mortality levels. Due to improved survival rates and historically high fertility levels, there are more women of reproductive age today than ever before. This contributes to a relatively large number of births, even if these women have fewer children on average. 

This means that the world population will continue to grow for decades to come. This in turn will lead to various challenges related to resource management, infrastructure strain, environmental impact, and social issues.


According to the UN, what are the 10 countries with the largest population?

India, China, United States, Indonesia, Pakistan, Nigeria, Brazil, Bangladesh, Russia, and Ethiopia.

What factors contribute to population growth?

Factors like birth rates, death rates, and immigration can all affect population growth.

How do these countries manage their large populations?

Strategies to manage the population include urban planning, healthcare initiatives, educational programs, and economic policies designed to promote growth and stability.
