Projected Rates of World Population Increase
Projected Rates of World Population Increase
The natural rate of increase of a population is found by subtracting the death rate per 1000 people from the birth rate per 1000 people. Different factors affecting birth and death rates, such as fertility, disease, war, and so on, impact the rate of natural increase of the population. You can see the rate of natural increase in the top graph. In the bottom graph, you can choose a different starting year to simulate how the world's population would be affected in the following three years if conditions were to stay constant.
