Answers

This graph shows the changes in the world’s population since the year 1750.
It shows that the number of people in the world is increasing.
It also shows that this number is increasing at a faster rate.
Each year the number of extra people on the planet is greater than in the previous year.
As well as showing the world’s population change, it also shows the population change in the more developed and less developed world.
The number of people in developed countries has grown from nearly 200 million in 1750 to 1200 million in 2012.
The population grew very quickly between 1875 and 1960.
The number of people in developing countries has grown from over 500 million in 1750 to 6000 million in 2012.
This population grew more slowly than in developing countries until 1925. Since then, it has grown at a very rapid rate.
