Which term refers to the number of live births per woman in a specific age group in a given year, expressed per 1000 women in that age group?

• A. Birth rate per 1000 women in a year
• B. Age specific fertility rate (ASFR)
• C. Crude birth rate
• D. General fertility rate

Answer: (B)

Age Specific Fertility Rate measures the number of live births to women in a specific age interval in a given year per 1,000 women in that age interval. This focuses on fertility patterns by a particular age group, revealing how childbearing varies across ages rather than across the entire population or all reproductive ages. The other terms mix in broader populations—crude birth rate uses total population, and general fertility rate uses all women of reproductive age—so they don’t reflect births per 1,000 women within a single age band.
