The Most Populated Countries in the World

The Most Populated Countries in the World

Want to know which are the world’s most populated countries? Here’s a list of the 15 most populated countries in the world.

The world population continues to grow, and currently, there are 7.7 billion people living on our planet, and experts estimate that we will be almost 10 billion people by 2050, and by 2100 it is estimated that there will be 11.2 billion people in the world. 

The low fertility rate in developed countries is likely to continue, and for developing nations the population growth is likely to increase until the middle and lower classes achieve a better standard of living, especially in Africa, which is the fastest-growing continent at the moment.

10. Mexico

Only Mexico City is home to more than 20 million residents if including the metro area, and the total population of Mexico amounts to circa 129 million people.

3. USA

The USA is a big country in every aspect, they are the most powerful and rich country in the world, so it might not come as a surprise that it’s also one of the most populated countries in the world with 327 million people living in the United States of America. 

It’s the most populous country in North America, and what’s even more interesting is the fact that it’s the number one country when it comes to immigrants.

2. India

India is another country where the population is rising quickly, and in a couple of years, India is expected to overtake the position as the most populous country in the world.

Right now, there are 1.3 billion people living in India, and although the poor and middle class improve their living standards each year, there is no expectation that the population will decrease, quite the opposite as the population is aging and the fertility rate continues to rise.

1. China

The most populated country in the world is China with more than 1.4 billion people. It’s a massive country where the economy has developed quickly for the last decades. 

China has once again become a superpower, and if they hadn’t put in the policy of 1 child, the population would’ve probably been even larger than what it is today.

China’s population is equal to 20% of the Earth’s total population, and beyond the Chinese people actually residing within the country, there are many Chinese people living across the globe as well.

More about the most populated countries in the world

As already mentioned previously in this article, the most populous countries in the world have a high fertility rate in general with a few exceptions of the U.S and Japan. In general, the more developed a country becomes, the lower the fertility rate will get.

This has been true to Western societies which almost all are facing a decline in population growth, whereas almost all non-developed countries are having an increase in population growth.

This is mostly because of two reasons, medical care is getting improved which means that life expectancy is increasing in non-developing countries, and the number of death among children lowers as well.

On top of this, the old habits and culture of large families are still prevalent in these countries, especially among poor families since they’re dependent on children helping them with work and supporting the family.

This is a challenge for many of the most populated countries in the world, especially because the population growth continues while people live longer and fewer children die as well, which means more resources is needed, which is not always possible due to lack of infrastructure, corrupt governments and lack of a functioning society.

As for developing countries, population growth is declining in general, even though people live longer. But at the rate of people improving their living standard, it is very likely that each family will only get 1-2 children. There are also some mildly alarming reports on an increase of people that can’t produce offsprings.

This list of the most populated countries in the world in 2019 is likely to be a lot different in 2029.
