Population growth

The graph shows population growth in richer and poorer countries between 1750 and 2150. Overall the growth in poorer countries has increased sharply.

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. By 2000 the total figure was 6.1 billion, 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.

Finally, the graph shows that the total population has increased and will continue to increase in both countries rich and poor and the increase will be more in the less developed countries than in undevelopment countries.
