The answer is to subtract the birth rate from the death rate.
The difference between the birth rate and the death rate of a country or place is called the natural increase. The natural increase is calculated by subtracting the death rate from the birth rate. The rate of natural increase is given as a percentage, calculated by dividing the natural increase by 10.
The rate of natural increase (RNI) is a measure of how quickly a population is growing or declining. However, the RNI does not factor in population change resulting from immigration or emigration – it is determined solely by the difference between birth and death rates in a region.
