RATE OF NATURAL INCREASE

Statistics Directorate    
Definition:
The rate of natural increase refers to the difference between the number of live births and the number of deaths occurring in a year, divided by the mid-year population of that year, multiplied by a factor (usually 1,000).

It is equal to the difference between the crude birth rate and the crude death rate. This measure of the population change excludes the effects of migration.
