Which one of the following fertility-related statistics most appropriately gives the approximate magnitude of 'completed family size'?
Total Fertility Rate (TFR)
TFR is the average number of children a woman would bear if she passed through her entire reproductive span (15-49 years) at current age-specific rates. Because it sums fertility over the whole reproductive life, it is the best index of completed family size. TFR = 5 x sum of ASFRs (per woman). India's TFR is about 2.0 (NFHS-5), below replacement level of 2.1.
TMFR restricts the denominator to married women, so it measures fertility within marriage only. NRR counts surviving daughters, not total children; NRR = 1 means replacement, so it measures generational replacement, not family size. ASFR is fertility in one narrow age group (e.g. 20-24 years) per 1000 women, a building block of TFR rather than a lifetime summary.
Key point: TFR approximates completed family size; NRR measures replacement through surviving daughters; GFR and ASFR are age-restricted intermediate measures.
