Published by SEDAC | National Aeronautics and Space Administration | Catalog Last Checked: June 02, 2026 at 07:32 PM | Dataset Last Updated: July 14, 2025
The Natural Resource Protection and Child Health Indicators, 2020 Release, is produced in support of the U.S. Millennium Challenge Corporation as selection criteria for funding eligibility. The Natural Resource Protection Indicator (NRPI) and Child Health Indicator (CHI) are based on proximity-to-target scores ranging from 0 to 100 (at target). The NRPI covers 250 countries and is calculated based on the weighted average percentage of biomes under protected status. The CHI is a composite index for 194 countries derived from the average of three proximity-to-target scores for access to at least basic water and sanitation, along with child mortality. The 2020 release includes a consistent time series of NRPI scores for 2010 to 2020 and CHI scores for 2010 to 2019.
