Examines household land use and economic welfare in the Amazon basin, through the collection of a third round of panel data with improved spatial referencing and a new system for tracking households and individuals. The study area is typical of the arc of deforestation across the southern Brazilian Amazon. Data from this study were used to model the relationship between deforestation and household well-being, thereby gaining insight on welfare outcomes that also have implications for conservation policies. Face-to-face interviews were conducted with the residents of the Ouro Preto do Oeste region of the Brazilian state of Rondonia. Demographic questions focused on: education, age, household size, migration and place of birth of the residents. Other questions focused on the ownership of the lots, years of residency on the lots, household income sources, household wealth and assets, as well as household cost of living.
