This study is part of a global research effort entitled Consultations with the Poor, designed to inform the World Development Report 2000/1 on Poverty and Development. The research involved poor people in twenty-three countries around the world. The effort also included two comprehensive reviews of Participatory Poverty Assessments completed in recent years by the World Bank and other agencies. Deepa Narayan, Principal Social Development Specialist in the World Bank's Poverty Group, initiated and led the research effort. The global Consultations with the Poor is unique in two respects. It is the first large scale comparative research effort using participatory methods to focus on the voices of the poor. It is also the first time that the World Development Report is drawing on participatory research in a systematic fashion. Much has been learned in this process about how to conduct Participatory Poverty Assessments on a major scale across countries so that they have policy relevance. Findings from the country studies are already being used at the national level, and the methodology developed by the study team is already being adopted by many others.
