The chart above illustrates how world population has changed throughout history. View the full tabulated data.
At the dawn of agriculture, about 8000 B.C., the population of the world was approximately 5 million. Over the 8,000-year period up to 1 A.D. it grew to 200 million (some estimate 300 million or even 600, suggesting how imprecise population estimates of early historical periods can be), with a growth rate of under 0.05% per year. During the 20th century alone, the population in the world has grown from 1.65 billion to 6 billion.In 1970, there were roughly half as many people in the world as there are now.
