The files for this data set are available as global rasters in GeoTIFF, ASCII, and netCDF-4 formats. The ASCII and GeoTIFF data are available at the native 30 arc-second resolution and four lower resolutions: 2.5 arc-minute, 15 arc-minute, 30 arc-minute, and 1 degree. The netCDF-4 files are available at all resolutions except 30 arc-second. The data are stored in WGS84, geographic coordinate system (latitude/longitude).
Each downloadable is a compressed zip file whose contents vary depending on the chosen file format. For GeoTIFF (.tif) and ASCII (.asc), the data are packaged by age group at the desired resolution and include rasters of male, female, and total counts and densities. The netCDF-4 (.nc) data contain male, female or total population counts or densities at the desired resolution for all 5-year age groups up to 65+, as well as data quality layers and ancillary files. A separate documentation zip file contains PDF documentation, an Excel file (.xlsx) with country-level information and sources, and a text file (.txt) with a log of changes to the data set by version.
