The GMMS provides information found nowhere else on locations of ethnolinguistic peoples, and provides global coverage of at least first-level (states, provinces) sub-national political subdivisions, city and town locations, and over 50 additional layers of information that can be used to give geographic context to your maps.
Also available are statistical/demographic databases from many research sources in the Christian ministry community, including Wycliffe/SIL, Operation World/Patrick Johnstone, and the International Mission Board of the Southern Baptist Convention.
