Health Index is a weighted composite score incorporating 24 indicators covering key aspects of health performance. Health Index comprises of select indicators in three domains: (a) Health Outcomes; (b) Governance and Information; and (c) Key Inputs and Processes. The indicators are selected on the basis of their importance and availability of reasonably reliable data at least annually from existing data sources such as the Sample Registration System (SRS), Civil Registration System (CRS) and Health Management Information Systems (HMIS). A Composite Index is calculated as a weighted average of various indicators, focused on measuring the state of health in each state and UT for a Base Year (2018-19) and a Reference Year (2019-20)

Uttar Pradesh with the lowest Overall Reference Year (2019-20) Index Score ranked at the bottom (Rank 19) in Overall Performance, however, it ranked at the top in terms of Incremental Performance by registering the highest incremental change from the Base Year (2018-19) to Reference Year (2019-20). On the other hand, Kerala and Tamil Nadu were top two performers in terms of Overall Performance with the highest Reference Year (2019-20) Index Scores but ranked twelfth and eight respectively in terms of Incremental Performance. Telangana performed well both in terms Overall Performance as well as Incremental Performance and secured the third position in both instances. For the fourth consecutive round Kerala emerged as the best performer in terms of Overall Performance. Among the Smaller States, Mizoram emerged as the best performer in Overall Performance as well as Incremental Performance while among UTs, Delhi and Jammu & Kashmir ranked among the bottom UTs in terms of Overall Performance but emerged as the leading performer in terms Incremental Performance (Figures ES.1, ES.2 and ES.3).
