Based on data from the United Nations, the world population in some countries have a rise. We can see that the graph shows 6 areas illustrated with colourful lines. The red line shows the growth of African's population. In 20 years, 1987 to 2007, it increased from 0.5 billion to almost 1 billion. Then the lower level was Europe with green line that had no significant change in 0.75 billion people. Then in the same time, the areas that had a levelling out in population growth were America latin and Caribia, North America, West Asia with the number of 0.5, 0.25, 0.12 billion respectively. I supposed that the increase of Asia pacific population was caused both by large area and the density of the nations there.
