The General Fertility Rate differs from the Crude Birth Rate primarily because the General Fertility Rate uses which denominator?

• A Total mid-year population of the area
• B Live births occurring in the previous year
• C Married women of all ages
• D Women aged 15 to 44 years in the population ✓

Explanation

The General Fertility Rate is defined as the number of live births per 1000 women of reproductive age, taken as 15 to 44 years in Park's textbook. It removes the large non-reproductive segment of the population that dilutes the Crude Birth Rate, making it a more precise fertility measure. Note that some international sources use 15 to 49 years, but Indian examination convention follows Park. Option A is the denominator of the Crude Birth Rate itself, which is precisely what GFR avoids.
