The Chronic Poverty and Long Term Impact Study in Bangladesh project, which focuses on 102 villages characteristic of rural Bangladesh, aims to further our understanding of the economic, social, and political processes that shape chronic poverty in Bangladesh together with the impact of selected anti-poverty interventions on poverty dynamics. After initial community level fieldwork approximately 1,907 core households first surveyed in 1994, 1996, or 2000 were interviewed in late 2006 to ascertain how their living standards, endowment and other characteristics have changed over time, and what role selected interventions have had on their welfare trajectories.
