Net Reproductive Rate Calculator

Formula

The formula to calculate the net reproductive rate (NRR) is:

\[ NRR = \frac{(B - D)}{P} \times 100 \]

Where:

\( NRR \) is the net reproductive rate (%)
\( B \) is the number of births
\( D \) is the number of deaths
\( P \) is the population size

What is Net Reproductive Rate?

The net reproductive rate (NRR) is a measure of the percentage of a given population that is reproducing. It is calculated by subtracting the number of deaths from the number of births, dividing this result by the population size, and then multiplying by 100.

Example Calculation

Let's assume the following values:

Number of Births (B): 500
Number of Deaths (D): 200
Population Size (P): 10000

Using the formula to calculate the net reproductive rate:

\[ NRR = \frac{(500 - 200)}{10000} \times 100 = \frac{300}{10000} \times 100 = 3\% \]

The Net Reproductive Rate (NRR) is 3%.
