Published by SEDAC | National Aeronautics and Space Administration | Metadata Last Checked: August 03, 2025 | Last Modified: 2025-07-17
The Natural Resource Protection and Child Health Indicators, 2021 Release, is produced in support of the U.S. Millennium Challenge Corporation (MCC) 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 135 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 2021 release includes a consistent time series of NRPI scores for 2017 to 2021 and CHI scores for 2010 to 2020.
