329478 individual houses mapped from high resolution images obtained from Google Earth or Bing using Terraincognita. Most of the images were taken between 2012 and 2016, and so the mapping data for some areas could be updated when newer images become available. The mapping was done in ArcView, QGis or ArcMap, each identified household being mapped as a separate point object. Certain urban areas were too large or dense for individual houses to be mapped, and so the populated areas of these towns were mapped as polygons. In the absence of census data on the number of people in these urban areas, a figure of 3,000 people per square kilometer was used an approximate density figure for purposes of mapping and comparison with rural areas.
