These are the country-level datasets used in the paper "A Comprehensive Assessment of Universal Health Coverage in 111 Countries. A Retrospective Observational Study". The paper assesses Universal Health Coverage (UHC) achievement in 111 countries using an index that captures both health service coverage (SC) and financial protection (FP) from high out-of-pocket medical spending. We measure SC by a weighted geometric average of four prevention and four treatment indicators, FP by the incidence of ‘catastrophic’ health expenditures (those exceeding 10% of household consumption or income), and a country’s UHC performance as a geometric average of the SC index and the complement of the incidence of catastrophic expenditures. Where possible, we adjust SC for inequality, penalizing high-inequality countries. We obtain the bulk of our data points originate from household surveys.
