Cities growth from 1950 to 2015

This bar graph shows the growth of population in different cities in the world from 1950-2015.

The three highest cities in population in 2015 are predicted to be Tokyo, Bombay and Lagos. They are above 20 millions. The lowest cities in the same year are New York, Cairo and London. In 1950 London’s population was 8 million and it will fall in 2015 to 7 million. Cairo in 1950 was below 5 million but in 2015 will increase to about 13million.New York was a steady rise in 1970, 2000, 2015.Shanghi has growth of 10 million from 1950-2015.Between 1950 and 2015 Mexico City increase from less than 5 million to 18 million. The smallest cities in population in 1950 were Lagos, Bombay, Sao Paolo, Mexico City, Cairo and Shanghai; they were below 4 million. The city of Tokyo will have the same population from 2000 to 2015.

All in all, I think the city of Lagos has increased more than 22 times; that means the largest increase in population.
