This dataset contains the estimate of the surface area of land
in square kilometers per pixel, excluding permanent ice and water,
within each pixel, and was used to calculate the GPW v4.11 population density
datasets.
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 1 km) 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.
