# How to calculate General fertility rate (GFR) in Nepal General fertility rate (GFR) is more specific and refined form of fertility rate in comparison to crude birth rate (CBR). We take the total population of males and females ignoring the sex in denominator for calculating Crude Birth Rate (CBR). But calculating General Fertility Rate (GFR), we take only the female population of reproductive age who are expected to be mothers. Normally, in Nepal the women of 15 to 49 years of age are included in for calculating the general fertility rate. In some countries, the women of 15-44 years of age are included for calculating general fertility rate (GFR).

The General Fertility Rate (GFR) is the birth rate of women of child bearing age(age 15-49).  General fertility rate (GFR) is the total number of live births per thousand mid-year female population of reproductive age. The general fertility rate is calculated by dividing the total number of live births the total mid-year female population in a given year by the number of women aged 15 through 44 and multiplying the product by 1,000.

The following formula is used to calculate GFR.

GFR = B/Pf (15-19)* 1000

Where,

B = total number of live births in a place in a given year.

Pf 15-49 = total mid-year female population of reproductive age in a place in the same year

For example:

Suppose the total mid-year female population of reproductive age in Nepal in 2008 AD was 65,01,300 and the total number of live births in the same year was 8,66,450. Find out the general fertility rate (GFR) of Nepal in 2008.

Here,

Total number of live births in Nepal in 2008 (B) = 8,66,450

Total midyear female population in the same year (Pf 15-49 ) = 65,01,300

Now,

GFR  = B/Pf (15-19)* 1000

= 866450/6501300 * 1000

= 133.27

So, GFR = 133.27 births per thousand women of reproductive age.

Therefore, about 133 births took per 1000 women of reproductive age (15-49) in 2008.
