This document summarizes 6 years of community mapping efforts in rural Tanzania led by Crowd2Map and Tanzania Development Trust. Over 16,000 volunteers have mapped over 5.3 million buildings, 300,000 km of roads, and 12,000 sq km across Tanzania. The mapping helps connect over 10,000 people living in areas not shown on any map. Through training local digital champions, the maps also help protect girls from female genital mutilation and gender-based violence by allowing them to find safe houses. In total, the mapping efforts have helped over 3,000 girls avoid being cut and coincided with a 75% reduction in FGM death rates over 5 years.
