The dataset has grown over time from the first dataset published in 2000 which pulled data from 42 surveys and one type of survey, covered just 42 countries, and included just 34 indicators, which all concerned maternal and child health. In 2013, for the first time, the database included household out-of-pocket health expenditures, noncommunicable disease indicators (NCD), and data from high-income countries. A major extension in 2018 and a subsequent 2019 update increased the number of household surveys included in HEFPI to over 1,700, covering 197 countries, and added richer NCD data as well as more extensive data on household out-of-pocket expenditures. The current 2022 version of the HEFPI database continues this trend, sourcing from almost 1,900 household surveys and covering 204 countries, and extending the number of indicators to 104, including new indicators of financial protection and, for the first time, indicators of effective health coverage and quality. Finally, the 2022 version of the database provides insights into regional inequities in indicators by making them available by urban and rural area of residence and by subnational regions.
