Enter the number of live births and the female population ages 15-44 into the General Fertility Rate Calculator. The calculator will evaluate the General Fertility Rate.

## General Fertility Rate Formula

The following two example problems outline the steps and information needed to calculate the General Fertility Rate.

FR = LB / P * 1000
• Where FR is the General Fertility Rate (births per 1000 women)
• LB is the number of live births
• P is the female population ages 15-44

To calculate the general fertility rate, divide the number of liver births by the female population ages 15-44, then multiply by 1000.

## How to Calculate General Fertility Rate?

The following example problems outline how to calculate General Fertility Rate.

Example Problem #1:

1. First, determine the number of live births.
• The number of live births is given as: 100,000.
2. Next, determine the female population ages 15-44.
• The female population ages 15-44 is provided as: 2,000,000.
3. Finally, calculate the General Fertility Rate using the equation above:

FR = LB / P * 1000

The values provided above are inserted into the equation below and computed.

FR = 100,000 / 2,000,000 * 1000 = 50 (births per 1000 women)

Example Problem #2:

For this problem, the variables required are provided below:

number of live births = 150,000

female population ages 15-44 = 3,000,000
