Replacement Fertility Rate

Introduction to Replacement Fertility Rate Calculator

The replacement fertility rate is the average number of children that must be born to a woman in order to replace the population itself, taking into account mortality and other factors. In this formula, n represents the number of age groups considered, and age represents the age of each group. The result is typically a decimal value indicating the number of children per woman needed to sustain the population.

Parameter usage:

• ages = array of ages in each age group

Output:

• Replacement Fertility Rate = average number of children per woman needed to sustain the population

Data validation

The ages should be non-negative integers. At least one age must be greater than zero.

Summary

This calculator calculates the replacement fertility rate based on the ages of different groups within the population, providing insights into population sustainability.
