History of world population growth and some future forecasts

Top 10 most populous countries in the world in 2022
The entire history of human population growth

The chart above illustrates how the world’s population has changed throughout history.

At the dawn of agriculture, around 8000 BC, the world population was about 5 million people. In the 8,000-year period until BC, it grew to 200 million (some estimates are 300 million or even 600, suggesting that population estimates of early historical periods may not be accurate). like), with a growth rate of less than 0.05% per year.

A tremendous change happened with the industrial revolution: while it took the time of the entire human history until about 1800 for the world’s population to reach one billion, the second billion was achieved in just 130 years (1930), the third billion in 30 years (1960), the fourth billion in 15 years (1974), and the fifth billion in just 13 years (1987).

  • In the 20th century alone, the world’s population increased from 1.65 billion to 6 billion.
  • In 1970, the number of people in the world was about half of what it is today.
  • Due to the reduced growth rate, it will now take more than 200 years to double again.
The annual rate of world population growth

The world population, as of 2020, is growing at a rate of about 1.05% per year (down from 1.08% in 2019, 1.10% in 2018 and 1.12% in 2017). The current average population growth is estimated at 81 million people per year.

The annual growth rate peaked in the late 1960s, when it was around 2%. The rate of increase has nearly halved since then and will continue to decline in the coming years.

As a result, the world’s population will continue to grow in the 21st century, but at a much slower rate than in the past. The world’s population doubled (100% increase) in the 40 years from 1959 (3 billion) to 1999 (6 billion). It is estimated that it will take nearly 40 more years to grow by another 50% to become 9 billion by 2037.

The latest world population projections show that the world population will reach 10 billion people by 2057.
