Citizen-generated data can complement official data sources and close data gaps. In Kenya, the Kenya National Bureau of Statistics (KNBS) is building its capacity to use these alternative data sources. This report describes how partners from KNBS, the SDGs Kenya Forum, PARIS21 and Partners for Review worked together on a project to build and strengthen capacities within the national statistical system (NSS) and actors of the extended data ecosystem in Kenya to use new and alternative data sources to improve national reporting on the Sustainable Development Goals.
