Global Deprivation Index: Child Dependency Layer

GRDI CDR Constituent Raster
land NASA VEDA COG
In plain English

What it measures. A global map of the child dependency ratio, a measure of how many children depend on the working-age population, used as one ingredient in a worldwide index of relative deprivation.

How it's made. Built as a gridded data layer for the Global Gridded Relative Deprivation Index, combining demographic and census-based data onto map cells.

How & where you'd use it. Helps identify disadvantaged areas to guide aid, development, and disaster-vulnerability planning.
