Data sources This database was initially produced for the UNEP/GRID-WRI-NCGIA Africa Population Database. See the GRID-Sioux Falls web site at http://grid2.cr.usgs.gov The population figures for 1960-90 are, in turn, based on the OECD/Club du Sahel West Africa Long Term Perspective Study (WALTPS), and were estimated by Benoit Ninnin. The 1980 and 1990 estimates produced for this database were used to produce the P95E estimate. WALTPS pop estimates based on: Etude d'une Image - Long Terme de l'Afrique.
