Last Updated:

Travelling to different countries can be exciting and fun for a number of reasons.

Understanding their culture, history, beliefs and religion are just to name a few. 

But often, the population gets overlooked, it’s something that’s not really seen to be important for most. 

However, for those of you that find this sort of stuff interesting, and would like to understand a bit more about the world you live in, then this article’s for you. 

Here’s a list of the 10 most populated countries in the world: 


The 10 Most Populated Countries In The World

The list of countries and figures mentioned below have been compiled from various sources around the web, such as Wikipedia, Worldometres & World Population Review

These are the 10 most populated countries in the world:


10. Mexico – 128 Million

Most Populated Countries - Mexico

The tenth most populated country in the World is Mexico. 

With a current population of 128 million people, Mexico has overtaken Japan and the Philippines to claim its spot in the top ten. 

Mexico covers an area of approximately 1,972,550 square metres and holds roughly 1.63% of the world’s population.

It has a population density of around 66 per km², with the majority of the population aged between 25-54.

Mexico City, Itzapalpa and Ecetepec are the most densely populated cities in the country, holding around 16 million people combined. 


9. Russia – 146 Million 

Most Populated Countries - Russia

Next up, we have a country with 146 million people and a total land area of 16, 376,870 km². 

The population density in Russia roughly equates to nine people per km². 

Russia’s population is equivalent to approximately 1.89% of the worlds total population and it has an average median age of 38.8 years.

Like many countries, the majority of Russias population resides in urban areas, such as the capital city, Moscow, which has a population of 12.1 million people. 

Russia’s population isn’t expected to increase any time soon, in fact, it’s more likely to decline slowly over the next decade, with many experts predicting a total population of 140 million by 2030. 

However, government incentives have been put in place to offer new mothers monetary rewards for having three or more children.

So, we’ll just have to wait and see what happens.  


8. Bangladesh – 167 Million

Most Populated Countries - Bangladesh

Bangladesh is the eighth-most populated country in the world.

It has a total land area of 130,170 km² and roughly 1,250 people per km².

Dhaka is the capital city of Bangladesh, with a population of 14.4 million people.

The population of Bangladesh is equivalent to 2.11% of the total world population. 

The median age in Bangladesh is 26.1 years and at this current time, the country is growing at approximately 1%. 

By 2020, Bangladesh is expected to reach a population of approximately 170 million and 186 million by 2030.


7. Nigeria – 202 Million

Most Populated Countries - Nigeria

The current population of Nigeria is approximately 202 million people. 

Over 50% of people, 51.2% to be exact, live in urban areas. 

Nigeria has many cities, five of which have a population of more than one million people. 

Lagos is Nigeria’s capital city and by far the largest city in Nigeria. It has roughly 17.5 million people.

The median age of Nigeria is 17.9 years old and there are approximately 221 people per km².

Nigeria has a total land area of 910,770 km² and its population is equivalent to 2.61% of the total world population. 

It’s predicted that Nigeria’s population is expected to hit 206 million by 2020 and 264 million by 2030. If that rate of growth continues, by 2036 Nigeria could cross the 300 million population threshold. 


6. Brazil – 211 Million

Most Populated Countries - Brazil

Brazil is the sixth most populated country in the world, with a current total population of 211 million.

It’s the largest country in South America, with a population density of 24.66 people per km².

Brazil covers a total area of 8,358,140 km² and holds roughly 25 people per km².

It has a median age of  31.8 years and 87.4% of the population is urban. 

Due to families deciding to wait longer to have children and more Brazilian woman entering the workplace, the birth rate in Brazil has fallen considerably since 1970.

The average birth rate today is 1.77 births per woman, which has fallen from 4 per woman in the 70s. 

It is expected that Brazil will continue to grow slowly until 2050, and then the impacts of a decline in birth rate will start to take effect and the population will begin to stagnate and or decrease.

Since the implementation of the one-child policy, Chinas growth rate has slowed down significantly. 

It’s predicted that it will continue to slow down and the population will begin to decrease by 2030 onwards. 

For now, we will just have to wait and see what happens. India is hot on its tail to take the title of the most populated country in the world. 



We hope you’ve enjoyed our list of the 10 most populated countries in the world. 

It probably wasn’t too surprising to see the usual suspects occupy the top three spots. However, some of the others on the list did surprise us, like Mexico and Nigeria. 

Keep an eye on these countries over the coming years, and watch how their position fluctuates, due to migration, death and birth rates. 

Here’s a quick recap of the 10 most populated countries in the world:

  1. China – 1.43 Billion
