Kibera, thought to be the largest slum in Africa and among the five largest slums in the world, is composed of dozens of villages and upwards of one million residents. While residents struggle with lack of water and sanitation facilities, regular flooding, threats of evictions, and other challenges, the community also has strong local leaders, innovative entrepreneurs, and creative young people.

Community Mappers grew out of an organic initiative during the COVID-19 pandemic to monitor and address severe and dynamic community needs. The founder, Nicera Wanjiru Kimani, has more than a decade of community organising, data collection, and training experience with Slum Dwellers International (SDI) - Kenya.
