The NITI Aayog Health Index is a composite measurement tool developed by the National Institution for Transforming India (NITI Aayog), the Government of India's apex public-policy think tank that replaced the Planning Commission on 1 January 2015 by a Union Cabinet resolution. Titled "Healthy States, Progressive India," the Index was created jointly by NITI Aayog, the Union Ministry of Health and Family Welfare, and the World Bank, with technical validation by a domain expert group. The first edition, covering the base year 2014–15 and reference year 2015–16, was released in February 2018. The instrument draws its mandate from NITI Aayog's stated objective of promoting cooperative and competitive federalism, using ranked benchmarking to spur states to improve service delivery rather than relying on top-down directives. It aligns with India's commitments under Sustainable Development Goal 3 (good health and well-being) and the National Health Policy 2017.
The Index is constructed as a weighted composite of indicators grouped under three domains: Health Outcomes, Governance and Information, and Key Inputs and Processes. Health Outcomes, which carries the highest weight, includes measures such as the neonatal mortality rate, under-five mortality rate, maternal mortality ratio, sex ratio at birth, total fertility rate, full immunisation coverage, and the proportion of low-birth-weight babies. Governance and Information captures institutional stability and data systems, including the average tenure of key administrators such as the Mission Director of the National Health Mission and the Chief Medical Officer, plus data integrity for the Health Management Information System. Key Inputs and Processes covers infrastructure and human resources, including vacancy levels for medical officers and specialists, functional First Referral Units, and accreditation of public health facilities. Each indicator is normalised, weighted, and aggregated into a score on a scale of 0 to 100.
A defining methodological feature is that the Index reports two distinct measures: the incremental performance (the change in score between the base year and the reference year) and the overall performance (the absolute composite score for the reference year). This dual structure rewards both high achievers and rapid improvers, ensuring that a low-base state showing strong year-on-year gains receives recognition alongside a consistently high-ranking state. To ensure fair comparison, states are ranked within three peer groups: Larger States, Smaller States, and Union Territories. Grouping accounts for structural differences in population, geography, and administrative capacity, so that small states are not measured against the scale challenges of the most populous ones.
Successive editions have produced widely cited rankings. In the fourth round, released in December 2021 and covering the reference period 2019–20, Kerala ranked first among Larger States on overall performance, with Tamil Nadu and Telangana following, while Uttar Pradesh recorded the lowest overall score but among the strongest incremental improvements. Among Smaller States, Mizoram and Tripura performed strongly, and among Union Territories the Dadra and Nagar Haveli and Daman and Diu and Delhi featured prominently. NITI Aayog's then Vice-Chairman and CEO presided over the launches, and the reports were prepared in coordination with the Health Ministry's data on the Health Management Information System and the National Family Health Survey conducted by the International Institute for Population Sciences in Mumbai.
The Health Index must be distinguished from adjacent NITI Aayog instruments. It differs from the SDG India Index, which tracks all seventeen Sustainable Development Goals at a broader level, whereas the Health Index focuses exclusively on the health sector with deeper, domain-specific indicators. It is also separate from the School Education Quality Index and the Composite Water Management Index, which apply the same competitive-federalism logic to other sectors. Unlike the National Family Health Survey, which is a primary household survey generating raw data, the Health Index is a derivative composite that aggregates administrative and survey data into a single ranked score. Practitioners should not conflate the Index with the Ayushman Bharat scheme, which is a programme rather than a measurement framework.
The Index has attracted methodological scrutiny. Critics note that several indicators depend on the Health Management Information System, whose data quality varies across states, potentially distorting comparisons; the reliance on tenure of officials as a governance proxy has been questioned as a narrow measure of institutional health. The five-year gap between certain rounds and reliance on lagged survey data limit real-time policy use. The COVID-19 pandemic exposed dimensions of health-system resilience, such as critical-care capacity and surveillance, not fully captured by the original indicator set, prompting discussion of revised metrics. NITI Aayog has periodically refined the indicator basket and weights between rounds, which complicates strict longitudinal comparison across editions.
For the working practitioner, the Health Index is a primary reference for assessing comparative state health performance and for the General Studies Paper III economy and governance components of the UPSC Civil Services Examination, where cooperative and competitive federalism, social-sector indicators, and NITI Aayog's role are recurring themes. Desk officers and policy researchers use the rankings to identify lagging states, target central transfers, and frame conditionalities under centrally sponsored schemes. Its rankings inform parliamentary debate, journalistic coverage of federal disparities, and the design of incentive-linked financing. Understanding both its construction and its limitations allows the analyst to deploy the Index as evidence while avoiding overinterpretation of single-year movements.
Example
In December 2021, NITI Aayog released the fourth round of its Health Index, in which Kerala topped the Larger States category on overall performance while Uttar Pradesh recorded the strongest incremental improvement.
Frequently asked questions
The Index aggregates indicators across Health Outcomes, Governance and Information, and Key Inputs and Processes. Health Outcomes carries the highest weight and includes neonatal and under-five mortality, maternal mortality ratio, sex ratio at birth, and immunisation coverage.
