Gridded Population of the World, Version 3 (GPWv3): National Administrative Boundaries
Entry ID:
CIESIN_SEDAC_GPWv3_NADMINBND
Summary
Abstract:
Gridded Population of the World, Version 3 (GPWv3) Centroids consists of estimates of human population counts and densities for the years 1990, 1995, 2000, 2005, 2010, and 2015 by administrative unit centroid location. The centroids are based on the 399,781 input administrative units used in GPWv3. In addition to population counts and variables, the centroids have associated administrative unit names and the land area of contained within the administrative unit. 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 shapefiles (SHP) are available from the NASA Socioeconomic Data and Applications Center (SEDAC). Purpose: To provide a quantitative measure of the input resolution of administrative units used for GPWv3.

Quality
The data were collected by GPS survey by Eric Woehler (AAD) using a Garmin 12XL receiver (not differentially corrected) during the 2003/2004 field season. The point and polygon data represent nesting sites or colonies of flying birds and penguins. GIS data derived directly from the GPS data have q_info=562.
Additional data were eyed based on field observations of inaccessible ...
