Geographic Information Systems technology allows researchers and other users to compile layers of information into 'themes'. Thematic data layers are information data sets that have a common feature or attribute placed in the same layer of spatial data. This guide is arranged by general spatial themes. This guide is meant to be a starting point for finding spatial data that corresponds to a specific focus of a GIS analysis or map.
The U.S. Census Bureau’s International Data Base update provides demographic revisions for 23 countries. Ten of these countries are in sub-Saharan Africa, six are in Europe, and the rest are in the Middle East, North America, and Latin America and the Caribbean.
