Q. Examine how India's National Family Health Survey has shaped the understanding of reproductive health trends since the 1990s. (15 marks, 250-350 words)

Launched in 1992-93 and conducted by the International Institute for Population Sciences under the Ministry of Health and Family Welfare [1], the NFHS has, across five rounds, converted reproductive health from an assumption-driven policy field into an evidence-driven one — though blind spots remain.

Built a comparable time-series - Successive rounds retain a common core questionnaire, enabling three-decade trend tracking rather than one-off snapshots [1]. - Expanding samples and district-level estimates from NFHS-4 onward shifted planning from national averages to district targeting [2].

Reframed the fertility narrative - Documented the fall in Total Fertility Rate from 2.2 (NFHS-4) to 2.0 (NFHS-5), below the replacement level of 2.1 [3]. - Recorded near-universal rise in family planning use across states, shifting discourse from population "control" to reproductive choice [2].

Exposed service-delivery gaps - Tracked the surge in institutional births, while showing laggards such as Nagaland (~46%) and rising out-of-pocket delivery costs in several states [2]. - Flagged a declining sex ratio at birth in several states, sustaining scrutiny of PCPNDT enforcement [2].

Opened newer frontiers - NFHS-5 added abortion methods and reasons, menstrual practices and disability — widening "reproductive health" beyond maternal care [1]. - NFHS-based analyses of rising secondary infertility now inform a field WHO estimates affects 1 in 6 adults globally [4], complementing the regulatory turn marked by the ART (Regulation) Act, 2021 and Surrogacy (Regulation) Act, 2021 [5].

Limitations - Self-reported, currently-married-women focus under-counts male infertility, unmarried persons and stigma-laden conditions. - Long inter-round gaps delay course correction; NFHS is a survey, not a registration system.

The NFHS has thus supplied the empirical backbone for policies from the National Population Policy to reproductive-health targets under SDG-3. Going forward, shorter survey cycles, integration with Civil Registration System data, and dedicated modules on infertility and men's health would let it capture the next demographic transition as sharply as it captured the last.
