The raster data sets are now available in ASCII (text) format as well as in GeoTIFF format. A vector data set of the center point locations (centroids) for each of the input administrative units and a raster of national level numeric identifiers are included in the collection to share information about the input data layers. In addition, rasters are available for basic demographic characteristics (age and sex), data quality indicators, and land and water areas. All estimates of population counts and population density have also been nationally adjusted to population totals from the United Nation’s World Population Prospects: The 2015 Revision. Separate rasters are available for population counts and population density consistent with national censuses and population registers, or alternative sources in rare cases where no census or register was available.
