The National Family Health Survey (NFHS) is a household sample survey run by the International Institute for Population Sciences (IIPS), Mumbai, for the Ministry of Health and Family Welfare. NFHS-6 interviewed 679,238 households, 716,397 women and 100,977 men in two fieldwork phases (28 May 2023 – 26 Feb 2024 and 7 Feb 2024 – 31 Dec 2024), using a two-stage sample designed for national, State/UT and district estimates, with height, weight, blood pressure and random blood glucose measured by trained health investigators. Every value is a weighted survey estimate, a percentage of the stated population group, not a count of services. NFHS-6 indicator 86, under 'Hypertension among Adults (age 15 years and above)', Women: 'Elevated blood pressure (Systolic ≥140 mm of Hg and/or Diastolic ≥90 mm of Hg) or taking medicine to control blood pressure (%)'. Blood pressure is measured by the survey team during the household visit. Source: NFHS-6 fact sheet compendium, '<Place> - Key Indicators', indicator 86: the 'NFHS-6 (2023-24) Total' column for the 2023-2024 value and the 'NFHS-5 (2019-21) Total' column for the 2019-2021 value. The NFHS-5 figure is the publisher's own restatement printed on the NFHS-6 sheet (the original NFHS-5 State fact sheets are now behind a login on nfhsiips.in), and is cited as such. IHO stores totals only; the urban and rural NFHS-6 columns are not stored. Periods are stored as the national fieldwork windows: 2023-2024 (1 May 2023 – 31 Dec 2024) and 2019-2021 (17 Jun 2019 – 30 Apr 2021). Each State/UT was surveyed over a shorter stretch inside the NFHS-6 window (Appendix 2 of the compendium gives the dates; Kerala, for example, 4 Jul – 23 Dec 2023).
This is a crude prevalence among everyone aged 15 and over, not age-standardised: States with older populations (Kerala: 20.7% aged 60+ in NFHS-6) show higher rates partly because their people live longer. One measurement on one day, not a clinical diagnosis. A survey estimate carries sampling error: IIPS publishes relative standard errors for India only (Appendix 1), so small differences between States, or between rounds for a small State or UT, may not be real. The NFHS-6 fact sheets are provisional ('The results presented in the NFHS-6 Fact Sheets are provisional'); IIPS's final reports may revise them, and IHO records any change as a revision. Values the fact sheet prints in brackets rest on 25–49 unweighted cases and are stored as low-sample (shown with a warning, never scored); values it suppresses with '*' (fewer than 25 cases) are not stored. Manipur was not surveyed in NFHS-6, so it has no 2023-2024 value, and IHO does not carry its NFHS-5 value forward.
No value in this series has been revised since the observatory first archived it.

2 periods. Values exactly as published; nothing interpolated.
NFHS-6 prints its NFHS-5 value against the same indicator wording and footnotes, and the wording of this indicator did not change between the rounds. One design change affects every indicator: NFHS-6 selected urban first-stage units from the Urban Frame Survey blocks (2012-17) instead of Census enumeration blocks. Geography is the post-2020 map in both rounds (Jammu & Kashmir and Ladakh separate; Dadra & Nagar Haveli and Daman & Diu merged). Not comparable with HMIS figures for similarly named services, which count facility reports rather than surveying households.
