This paper describes the community-driven enumerations undertaken in Old Fadama, the largest informal settlement in Accra, which has long been threatened with eviction. After meeting with members of shack dweller federations from other nations, residents formed the Ghana Homeless People's Federation in 2003 (now known as the Ghana Federation of the Urban Poor (GHAFUP). Together with the NGO People's Dialogue on Human Settlements, they supported the first community-driven enumeration in Old Fadama in 2004 to counter the threat of eviction, by showing the large scale of economic activities in the community and the gap in accurate population data. This was followed by further enumerations, in 2006−2007 and in 2009, to counter new eviction threats from new city governments. These enumerations increased the residents' confidence, empowering them in terms of engagement with city government. They also changed government's perspective on informal settlements and helped shape policy away from forced evictions towards participatory relocations or rehabilitation.
