The total fertility rate (TFR) is the sum of age-specific fertility rates multiplied by the width of age interval. If 5-year groups, it is multiplied by:
Explanation:
TFR = 5 × Σ ASFR (per woman) if ASFR are computed per 1000 women per 5-year interval and divided by 1000 appropriately. Actually, if ASFRs are in per 1000, TFR = 5 × Σ ASFR_i / 1000.
