Population growth 1750 to 2150 World population growth

The line graph shows us a population Growth in Richer and poorer countries between years 1750 and 2150. This study done by UNITED NATIONS - world population prospects, the 1998 revision and estimates by the population reference Bureau.

In the first two centuries the population growth was very slow in poorer and richer countries. In 1750 the total world population was less than one billion in both poorer and richer countries. The population of less developed countries was three or four times greater than that of more developed countries. From 1950 to 2000 the population growth was very fast. By 2000 the population growth in poor countries was 5.1 billion, but only about 1 billion in richer countries. They estimate that by 2150 the total world population will be around or over 10 billion in poorer countries, but for richer countries it will remain about one billion. It may even drop 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.
