Best Answer

The rate of natural increase shows the rate at which people are added to a given population by births and deaths (ignoring migration). It is usually represented as follows: Rate of Natural Increase = Crude Birth Rate - Crude Death Rate This version of the rate of natural increase shows net addition of people from births and deaths per thousand people in the population. Occasionally it is re-expressed as the additions to the population per one hundred in the population (it is important to determine which version of the rate of natural increase is being used when you see it in the literature).
