How many people are there in the world? A very interesting question. Currently, there are almost 8 billion people roaming the Earth, and in the last 200 years, a massive increase in the population worldwide has occurred. 

In this article, we will dig deeper to see how many people there are in the world as of 2020 and what scientists estimate in the future. We will also take a closer look at where all these people are living on Earth.

World Population in 2020

Today, there are around 7.8 billion people living in the world. An exact number is not possible to get since some countries don’t have the resources and systems to accurately measure the number of citizens.

To put the number in another perspective, there were around 300 million people living on Earth in year 0. It wasn’t until the 1800s that the world population reached the first billion. 

The number one reason to the exponential growth in the 1800s and onwards is the industrial revolution. This gave developed countries a longer lifespan and the opportunity to save more lives. 

In the year 2000, there were around 6 billion people living on Earth, and in only 19 years, the world population has increased by almost 2 billion people.

How many people will live on Earth in the future? 

In a report from 2017, the UN estimate that the world population will increase to 9.8 billion before 2050. Some experts claim that we will reach 10 billion people in less time, whereas other experts claim that the number of births will lower as countries like China and India gets more developed. 

However, it’s not only in the largest countries in the world where the population increase. Africa is the continent that is estimated to have the biggest population growth in the future. Most experts estimate that there will be 1.3 billion more people in Africa before 2070. 

It’s also believed that the world population will start to flat out by the end of this century, but it’s also likely that we will be 13 billion people living on Earth by 2100. 

This is an important matter and it’s even more important to ask, how many people can our Earth sustain? Most statistics and reports tell us that we need to change our ways of living. Furthermore, food production will need to increase to feed our ever-growing population.

How Many People Are There in China?

China has a population of 1.39 billion people as of 2019, which makes it the most populated country in the world. The growth is a result of the major economic growth, increased life span, and better living conditions for a large part of the inhabitants. 

For some years, the central government limited Chinese people to only be allowed to have one child per family. Since 2016, each family is allowed to have two children.

Experts also claim that China will face the same decline in birth rate as most Western countries as the country become more developed.

How Many People Are There in India?

India is one of the fastest-growing countries in the world, and the gap between them and China is getting closer for each day that goes by. Currently, there are 1.3 billion people living in India.

The Indian economy is growing fast, and a large part of the population has seen improved living conditions. More people than ever before can meet their basal needs thanks to modern technology. 

With that said, there are still many Indians living in extreme poverty, and overpopulation is a big problem in Indian cities. The average life span in India is estimated at 68.8 years. This number is expected to be dramatically improved as the country becomes more developed in the years to come.

There are 327 million people living in the U.S, but contrary to India and China, the population growth here is almost stagnant. Last year, the United States saw the lowest growth rate in 80 years, with just a 0.62% increase.

With that said, the United States is still the third-most populated country in the world, and it’s still de-facto the biggest economy in the world. An average American is estimated to live until 79.3 years.
