It allocates population proportionally from census and administrative units, extrapolating data from the 2010 census round. Each grid cell's value, ranging from 0 to 970919, represents estimated persons. The data, provided by CIESIN, is accessible through Earth Engine using the identifier \"CIESIN/GPWv4/population-count\" with a five-year cadence. The dataset is now deprecated and superseded.\n"]]
