Net Reproduction Rate (NRR)

Introduction to Net Reproduction Rate (NRR) Calculator

The net reproduction rate (NRR) is a measure of the average number of daughters that would be born to a woman over her lifetime, given current age-specific fertility rates. It is calculated as the number of female births per female in the childbearing years divided by the number of females in the population at the midpoint of those years. The result is a ratio, usually expressed as a percentage.

Parameter usage:

• births= number of female births
• populationMidpoint= female population at the midpoint of childbearing years

Output:

• NRR= net reproduction rate

Data validation

The number of births and population midpoint should be greater than or equal to 0.

Summary

This calculator assists in evaluating the average number of daughters that would be born to a woman over her lifetime, based on current age-specific fertility rates.
