India's National Family Health Survey (NFHS-6) has omitted nearly 30 [1] data points and several key health indicators from its latest framework.
This reduction in data collection complicates the ability of researchers to track public health trends and evaluate the success of government welfare programs. The removal of critical metrics may create gaps in the national understanding of maternal and child health.
The omitted indicators include data on the sex ratio, cancer screening, and sanitation [2]. The survey also dropped metrics related to welfare scheme coverage, anaemia, and infant mortality [1]. These indicators previously served as benchmarks for measuring the effectiveness of public health interventions across different Indian states.
The Ministry of Health and Family Welfare said the omissions were intended to achieve data harmonisation across various surveys [2]. This process aims to align different data collection methods to ensure consistency in reporting.
However, policy analysts and researchers said the removals reduce transparency [1]. They said that the lack of these specific data points hinders effective health-policy planning and makes it difficult to identify emerging health crises in vulnerable populations [1].
The NFHS-6 was released during 2023-24 [1]. The survey is traditionally one of the most comprehensive sources of demographic and health data in the country, making the sudden absence of these indicators a point of contention among the scientific community.
“Nearly 30 data points and several key indicators were omitted from the NFHS-6 framework.”
The removal of these indicators suggests a shift in how the Indian government prioritizes and reports public health data. While data harmonisation can reduce redundancy, the loss of longitudinal data on infant mortality and sex ratios prevents a direct comparison with previous survey rounds, potentially masking negative trends or inflating perceived progress in social welfare.
