This graph shows the number of people in rich and poor countries between 1750 and 2150. It shows that the sharp increases started in 1950.

First the population of the developed and rich countries from 1750 till 1950 was much less than 1 billion but it increased to a peak of 1 billion in 2000 and they estimate that it will be stable till 2150. On the other hand, in the less developed and poor countries from 1750 till 1900, the population was 1 billion but it increased slightly to 2 billion in 1950 than it increased sharply to 6.1 billion in 2000 and they estimate that it will still be going up to 9 billion in 2150.

As we can see there are big differences between poor countries and rich countries. In 1950 the population of poor countries had increased but the rich countries become stable with small changes.
