GPWv411: Data Context (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 from 2000-2020 on a 30 arc-second grid.

  • This dataset categorizes pixels with estimated zero population based on census information, using a "data_context" band with values corresponding to classifications like parks, infrastructure, or uninhabited areas.

  • Population data is distributed using proportional allocation from census and administrative units, primarily based on the 2010 round of censuses.

  • Provided by NASA SEDAC at the Center for International Earth Science Information Network, the dataset is available under the CC-BY-4.0 license.

  • It has a resolution of 927.67 meters and includes a single band called data_context which provides the population context classification for each pixel.

Description

This dataset categorizes pixels with estimated zero population based on information provided in the census documents.

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.
