This study, which updates DIFFUSION OF SUSTAINABLE AGRICULTURE IN THE AMAZON [BRAZIL]: A PANEL DATABASE, 1996-2000 (ICPSR 3948), 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.

The data include a stratified random sample of households that reside within the 6,000 km2 region among the over 8,000 agricultural lots. In the initial data collection, a random sample of 171 households, stratified by the rural population of each of the 6 municipalities in the region, were interviewed over a 5-month period (September 1996 through January 1997). The sample was increased to 361 households, including 177 households from the original stratified sample (increasing due to split lots), 67 individuals (with information for their complete households) that moved from the original sample of lots and were tracked to their current location, and 117 new households within the original municipalities and new settlements within these municipalities that were added according to the original random sampling methodology.

survey data

There was only one refusal to participate in the survey in each year. The high response rate is attributed to two factors: first, culturally, Brazilians are generally hospitable to strangers, and second, because of the lack of contact with people, the farmers were generally pleased to communicate with outsiders. Many of the farmers do not leave their farms on a daily basis (especially during the rainy season) due to a lack of transportation, long distances to city centers, and poor road conditions.



2009-12-16 ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:

  • Created variable labels and/or value labels.
  • Created online analysis version with question text.
  • Checked for undocumented or out-of-range codes.


  • Data in this collection are available only to users at ICPSR member institutions.
