The red line indicates the growth rate of the global population starting at 1750, while the dark blue area shows the total number of people. The light blue area is a projection by the United Nations (UN) until the end of the century. As you can see, in the years 1750-1920 the growth rate was roughly stable. Then it shot up to 2.1% within 40 years where it reached its peak. Since 1960 it has declined rapidly to around 1.2% in 2015 and will continue to fall to 0.1% at the end of the century.
When you look at the chart below, we may even be able to reach that level of growth several decades earlier which would lead to a decline in population for the first time in centuries!
