The line graph shows the population growth in poorer and richer countries between, 1750 to 2150. That information’s were collected from the United Nations, World Population Prospect, in the 1998 Revision. Also, the Population Reference Bureau estimates it.
The world population in 1750 was less than one billion and the population of less developed countries was three to four times greater than that of more developed countries. The total figure was 6.1 billion by 2000, whereas in the developed countries there were about 1 billion more. In 2050 the world population is estimated to be close to 10 billion in less developed countries and it may rise more in the coming years. The more developed countries are estimated that it will be remained at about one billion and may even decreased.
To sum up, it is estimated that the total world population will increase dramatically over the next 50 years, but that this growth will be entirely in the less developed countries.
