net reproductive rate

,

NRR

A measure of whether a population is reproducing at a greater or lesser rate than needed for its replacement. It is determined by calculating the average number of surviving daughters born to the women in that population during their reproductive years. An NRR of 1 indicates that each woman in the population has one surviving daughter during her lifetime.
