How we score health gaps.
The Health Opportunity Score (HOS) will be a composite index built on the OECD Handbook framework for composite indicators. It adds three rescaled measures, each with a weight: Health Access (A), Health Outcomes (O) and Infrastructure Gap (I).
HOS = wA · A + wO · O + wI · I
The default weights are 35% for access, 40% for outcomes and 25% for infrastructure. They are provisional, and you can change them in the weighting tool.
Health Access
Primary and community health centres (PHCs and CHCs) per lakh people. A higher score means fewer facilities for the population.
Health Outcomes
A composite of infant mortality, maternal mortality and stunting. A higher score means worse health outcomes.
Infrastructure Gap
How far the number of hospital beds per person falls short of the national target. A higher score means a larger shortfall.
