Die Gridded Population of the World Version 4 (GPWv4), Revision 11, modelliert die Verteilung der globalen Bevölkerung für die Jahre 2000, 2005, 2010, 2015 und 2020 in Rasterzellen mit einer Größe von 30 Bogensekunden (ca. 1 km). Die Bevölkerung wird auf Zellen verteilt, indem die Bevölkerung aus Volkszählungs- und Verwaltungseinheiten proportional zugewiesen wird. Die Bevölkerungsdaten werden mit der detailliertesten räumlichen Auflösung erfasst, die aus den Ergebnissen der Volkszählungen von 2010 (zwischen 2005 und 2014) verfügbar ist. Die Eingabedaten werden extrapoliert, um Bevölkerungsschätzungen für jedes modellierte Jahr zu erstellen.
