Gridded Population of the World, Version 3 (GPWv3): Population Density Grid, Future EstimatesEntry ID: CIESIN_SEDAC_GPWv3_POPDENSFE
Abstract: Gridded Population of the World, Version 3 (GPWv3), Future Estimates consists of estimates of human population for the years 2005, 2010, and 2015 by 2.5 arc-minute grid cells. A proportional allocation gridding algorithm, utilizing more than 300,000 national and sub-national administrative units, is used to assign population values to grid cells. The future estimate population values are ... extrapolated based on a combination of subnational growth rates from census dates and national growth rates from United Nations statistics. All of the grids have been adjusted to match United Nations national level population estimates. The population density grids are derived by dividing the population count grids by the land area grid and represent persons per square kilometer. The grids are available in various GIS-compatible data formats and geographic extents (global, continent [Antarctica not included], and country levels). GPWv3 is produced by the Columbia University Center for International Earth Science Information Network (CIESIN) in collaboration with Centro Internacional de Agricultura Tropical (CIAT).
The data in ARC/INFO Grid, American Standard Code for Information Interchange (ASCII), Band Interleaved by Line (BIL) formats and maps in Portable Document Format (PDF) and Joint Photographic Experts Group (JPG) formats are available from the NASA Socioeconomic Data and Applications Center (SEDAC).
Purpose: To provide a time series of raster data on population projected to the year 2015 to facilitate data integration.
