Abstract:
Gridded Population of the World, Version 1 (GPWv1) consists of estimates of human population for the year 1994 by 5 arc-minute grid cells. The 4 products are raw and smoothed population counts and density, all of which are available in several GIS-compatible data formats at the global and continent levels. A straight majority rule gridding algorithm, utilizing approximately 19,000 national and sub-national administrative units, is used to assign population values to grid cells. The smoothing is performed using the pycnophylactic technique, which redistributes population counts among grid cells within administrative units by attracting population towards high-count areas. GPWv1 is produced by the National Center for Geographic Information and Analysis (NCGIA) with partial support from the Columbia University Center for International Earth Science Information Network (CIESIN).
Purpose: To provide global change researchers with consistent and detailed demographic data over a large area. These data should aid in the understanding of the human dimensions of environmental degradation.
