The Age-Specific Fertility Rate (ASFR) for women aged 20-24 years is calculated as:

• A Number of live births to women aged 20-24 per 1,000 married women aged 20-24
• B Number of live births to women aged 20-24 per 1,000 total population in that year
• C Number of live births to women aged 20-24 per 1,000 total live births in that year
• D Number of live births to women aged 20-24 per 1,000 women aged 20-24 in that year ✓

Explanation

ASFR is the number of live births per 1,000 women in a specific age group (usually 15-49 years) in a given year. The denominator is the total number of women in that age group, not just married women. This provides a more precise measure of fertility than the Crude Birth Rate by controlling for age structure.
