As recently as 12,000 years ago, there were only 4 million people worldwide. The chart shows the rapid increase in the global population since 1700.
It’s estimated to take approximately 14 years to reach nine billion in 2037 and 21 years to reach 10 billion in 2058. The latest UN medium projection expects that the world will not reach 11 billion people this century: it projects the population to peak at 10.4 billion in 2086 before falling again. Endnotes.
Actual global human population growth amounts to around 83 million annually, or 1.1% per year. [2] The global population has grown from 1 billion in 1800 to 8.1 billion in 2024. [ 3 ] The UN projected population to keep growing, and estimates have put the total population at 8.6 billion by mid-2030, 9.8 billion by mid-2050 and 11.2 billion by ...
The global population reached nearly 8.2 billion by mid-2024 and is expected to grow by another two billion over the next 60 years, peaking at around 10.3 billion in the mid-2080s. It will...

The size of the human population is one of the most important metrics to understand the world. This is true globally, regionally, nationally, and at local levels. Total numbers are often meaningless without the context of population figures.
The latest UN projections suggest that the world’s population could grow to around 8.5 billion in 2030 and 9.7 billion in 2050, before reaching a peak of around 10.4 billion people during the...
The current world population of 7.6 billion is expected to reach 8.6 billion in 2030, 9.8 billion in 2050 and 11.2 billion in 2100, according to a new United Nations report being launched today.
