Participatory statistics have come of age in a methodologically pluralistic world. In recent years participatory research has established its credentials as an approach - with an accompanying set of tools - in which local people themselves generate statistics. This book seeks to provide impetus for a step change in the adoption and mainstreaming of participatory statistics within international development practice. The time has come for participatory statistics to be recognized as the first and best option for a "win win" approach to data generation and analysis.
