Line graph population

Population growth 1750 to 2150


World population growth

The line graph shows population growth in richer and poorer countries between 1750 and 2150. It is based on the United Nations World Population Prospects, the 1998 Revision, and estimates by the Population Reference Bureau.

In 1750 the total world population was less than one billion and the population of less developed countries was three or four times greater than that of more developed countries. There was a dramatic increase in the second half of the twentieth century, with total population tripling from 2bn to 6.1bn, but only about 1 billion were in the more developed countries. The estimate is that by 2150 the total world population will be well over 10 billion but the total for the more developed countries will remain at about one billion and may even fall slightly.

It is estimated that the total world population will increase dramatically over the next 150 years but that this growth will be entirely in the less developed countries .
