GPWv411: Land Area (Gridded Population of the World Version 4.11)

  • The Gridded Population of the World Version 4 (GPWv4), Revision 11 dataset models the distribution of global human population for the years 2000, 2005, 2010, 2015, and 2020.

  • This dataset provides estimates of land area, excluding permanent ice and water, in square kilometers per pixel at a resolution of 927.67 meters.

  • Population data is distributed to grid cells using proportional allocation from census and administrative units and extrapolated to produce estimates for each modeled year.

  • The dataset is provided by NASA SEDAC at the Center for International Earth Science Information Network and is licensed under CC-BY-4.0.

  • This land area dataset was specifically used to calculate the GPWv4 population density datasets.

Description

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.

General Documentation

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.
