Published by SEDAC | National Aeronautics and Space Administration | Metadata Last Checked: January 31, 2026 | Last Modified: 2025-07-17
The Natural Resource Protection and Child Health Indicators, 2018 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 234 countries and is calculated based on the weighted average percentage of biomes under protected status. The CHI is a composite index for 199 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 2018 release includes a consistent time series of NRPI scores for 2014-2018 and CHI scores for 2010 to 2018.
