Intro

Prehistory

start from 50,000 BC

At the dawn of agriculture, about 8000 B.C., the population of the world was somewhere on the order of 5 million.

The slow growth of population over the 8,000-year period, from an estimated 5 million to 300 million in 1 A.D., results in a very low growth rate — only 0.0512 percent per year.

By 1650, world population rose to about 500 million, not a large increase over the 1 A.D. estimate.

By 1800, however, world population had passed the 1 billion mark, and it has continued to grow since then to the current 6 billion.
