The chart indicates the percentage of the population living in urban areas in the years 1950, 2007 and 2030. The first three columns show us the results in the whole world and the other columns show the results in different parts of the world. What is very obvious from the chart is that the number of people living in urban areas and also those moving to urban area are growing quite fast in all parts of the world and there isn't any part that the percentage has come down. It can also be seen that in North America and Latin America this percentage is higher than other parts. In comparison the proportion of people in cities in the rest of the world, Europe, Asia and Africa respectively have the highest percentages. The increase in the number of people in urban area is such that it is estimated that in the year 2030, approximately 60% of the people in the world will be living in urban areas.
