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]

Carry your answers up to 2 decimal places, and please show your work. 4.) Now that you know the values of R 0 & T, you can calculate the intrinsic rate of increase. Show your work. r = ln(R 0)/T = _____. 5.) If r = 0, the population is stable. If r > 0, the population is increasing.
