Age-specific Fertility Rate

The Age-specific Fertility Rate (ASFR) measures the number of live births to women within a specific age group, usually expressed per 1,000 women. It helps demographers and public health officials understand fertility patterns within different age brackets, enabling them to assess trends over time or differences within populations. For example, if the ASFR for women aged 25-29 is high, it indicates that many women in this age group are having children. This data is valuable for planning resources, healthcare services, and understanding social changes related to family and parenting.
