Population growth is one of the most important topics we cover at Our World in Data.
For most of human history, the global population was a tiny fraction of what it is today. Over the last few centuries, the human population has gone through an extraordinary change. In 1800, there were one billion people. Today there are more than 8 billion of us.
But after a period of very fast population growth, demographers expect the world population to peak by the end of this century.
On this page, you will find all of our data, charts, and writing on changes in population growth. This includes how populations are distributed worldwide, how this has changed, and what demographers expect for the future.
