The focus of community-based research lies in improving the evidence base for community-based programming. In 2009 a PeerCorps-led team in Dar es Salaam carried out an investigation into the patterns and risk factors for injuries among children and adolescents. A survey of approximately 2,000 households in Dar es Salaam was carried out in 15 areas of the city. These videos detail the workshop that preceded the actual fieldwork.
