Gridded Population of the World: Future Estimates (GPWFE)

Gridded Population of the World: Future Estimates (GPWFE) consists of estimates of human population for the years 2005, 2010, 2015 by 2.5 arc-minute grid cells. Population density estimates were also created using the GPWv3 land area grid for the year 2000 (also 2.5 arc-minute resolution). The data products include a population grid (raw counts), and a population density grid (per square km). These products vary in GIS-compatible data formats and geographic extents (global, continent [Antarctica not included], and country levels). Spatial reference metadata refers to global extent. 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. Additional global grids are created from the 2.5 arc-minute grid at 1/4, 1/2, and 1 degree resolutions. (Spatial reference metadata refers to global extent, 2.5 arc-minute resoulution). GPWFE is produced by the Columbia University Center for International Earth Science Information Network (CIESIN) in collaboration with the United Nations Food and Agriculture Programme (FAO) and the Centro Internacional de Agricultura Tropical (CIAT).
