The Age-Specific Fertility Rate (ASFR) is calculated for women in specific age groups. Which of the following correctly represents the formula for ASFR?

• A Number of live births to women in an age group / Total mid-year population × 1,000
• B Number of live births to women in an age group / Number of married women in that age group × 1,000
• C Number of live births to women in an age group / Total number of live births × 1,000
• D Number of live births to women in an age group / Number of women in that age group × 1,000 ✓

Explanation

ASFR = Number of live births to women in a specific age group / Number of women in that age group × 1,000. It measures the annual fertility rate for women of a given age group. The denominator is all women in that age group, not just married women, and not the total population.
