Description
The Gridded Population of World Version 4 (GPWv4), Revision 11 models the distribution of global human population for the years 2000, 2005, 2010, 2015, and 2020 on 30 arc-second (approximately 1km) grid cells. Population is distributed to cells using proportional allocation of population from census and administrative units. Population input data are collected at the most detailed spatial resolution available from the results of the 2010 round of censuses, which occurred between 2005 and 2014. The input data are extrapolated to produce population estimates for each modeled year.
The National Identifier Grid Represents the Census Data Source Used to Produce the GPWv4 Populations estimates. Pixels that have the same value reflect the same data source, most often a country or territory.

4* | 999* | An integer that represents the census data source used to produce the GPWv4.11 population estimates. Pixels (grid cells) that have the same value reflect the same data source, most often a country or territory. Note that these data represent the area covered by the statistical data as provided, and are not official representations of country or territory boundaries. |
