Methodology
How we score health gaps.
Scoring Framework
The Health Opportunity Score (HOS) is a composite index built on the OECD Handbook framework for constructing composite indicators. Three normalised dimensions — Health Access (A), Health Outcomes (O), and Infrastructure Gap (I) — are weighted and combined.
HOS = wA · A + wO · O + wI · I
Default weights: Access 35%, Outcomes 40%, Infrastructure 25%. Users can adjust these in the simulator to match their intervention priorities.
Dimension A
Health Access
PHC/CHC density per lakh population. Higher = fewer facilities relative to population.
Default weight35%
Dimension O
Health Outcomes
Composite of IMR, MMR, and stunting rates. Higher = worse health outcomes.
Default weight40%
Dimension I
Infrastructure Gap
Bed-to-population ratio gap vs national target. Higher = greater shortfall.
