Rate of natural increase

In Demography, the rate of natural increase (RNI), also known as natural population change, is defined as the birth rate minus the death rate of a particular population, over a particular time period.^[1] It is typically expressed either as a number per 1,000 individuals in the population^[2] or as a percentage.^[3] RNI can be either positive or negative. It contrasts to total population change by ignoring net migration.

This RNI gives demographers an insight into how a region's population is evolving, and these analyses can inform government attempts to shape RNI.
