GPWv411: Adjusted to Match 2015 Revision of UN WPP Country Totals (Gridded Population of the World Version 4.11)

  • This dataset provides global population estimates for the years 2000, 2005, 2010, 2015, and 2020 at a resolution of 30 arc-seconds per grid cell.

  • The population data is based on national censuses and registers, adjusted to align with the 2015 Revision of UN World Population Prospects country totals.

  • The dataset contains a single band representing the estimated number of persons per grid cell.

  • Due to the pyramid policy of MEAN, calculations on this dataset should be performed at native resolution to avoid information loss when zooming out.

  • The dataset is available from 2000 to 2020 with a cadence of 5 years and is provided by NASA SEDAC at the Center for International Earth Science Information Network.

Description

This dataset contains estimates of the number of persons per 30 arc-second grid cell, consistent with national censuses and population registers with respect to relative spatial distribution but adjusted to match the 2015 Revision of UN World Population Prospects country totals. There is one image for each modeled year.

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.
