It allocates population proportionally from census data, extrapolated to produce yearly estimates. The dataset provides the number of persons per grid cell, adjusted to match UN population projections, and is accessible via Earth Engine, using `ee.ImageCollection(\"CIESIN/GPWv4/unwpp-adjusted-population-count\")`.
