The picture shows a graphic of population of towns and cities in percentage of total. They have three different year, which is 1950, 2000, and 2030, and also have four different kind of the percentage, which is the whole world, Africa, Asia, and Latin America. The range of percentage is from 0 percent untill 90 percent.
For the whole world, there is 30 percent populations in 1950, 48 percent populations in 2000, and it will be 60 percent populations in 2030 as the prediction. For Africa, there is a 12 percent populations in 1950, 38 percent populations in 2000, and it will be 52 percent populations in 2030 as the prediction. For Asia, there is a 14 percent populations in 1950, 38 percent populations in 2000, and it will be 56 percent populations in 2030 as the prediction. And the last one, for the Latin America, there is a 42 percent populations in 1950, 70 percent populations in 2000, and it will be 80 percent populations in 2030 as the prediction.
The summary from the picture below is, the population will grow every year if we look from the history of the population. And the Latin America has grown faster than the other towns. However, there is no significant population different from each towns.
