The National Identifier Grid was reprocessed to remove artifacts from inland water.The netCDF files were updated to include the Mean Administrative Unit Area layer, the Land Area and Water Area layers, and two layers indicating the administrative level(s) of the demographic characteristics input data.Erroneous no data pixels in all of the gridded data were recoded as 0 in cases where census reported known 0 values.The extent of the final gridded data has been updated to a full global extent.In this release, several issues identified in the 4.10 release of December 2017 have been corrected as follows: The nine data sets of the current release are collectively referred to as the Revision 11 (or v4.11) data sets. GPWv4 is gridded with an output resolution of 30 arc-seconds (approximately 1 km at the equator). The raster data sets are constructed from national or subnational input administrative units to which the estimates have been matched. A set of estimates adjusted to national level, historic and future, population predictions from the United Nation's World Population Prospects report are also produced for the same set of years. The input data are extrapolated to produce population estimates for the years 2000, 2005, 2010, 2015, and 2020. It provides globally consistent and spatially explicit data for use in research, policy-making, and communications.įor GPWv4, population input data are collected at the most detailed spatial resolution available from the results of the 2010 round of Population and Housing Censuses, which occurred between 20.

The purpose of GPW is to provide a spatially disaggregated population layer that is compatible with data sets from social, economic, and Earth science disciplines, and remote sensing.
