Longitudinal Survey Data of Households in Ouro Preto do Oeste, Rondonia, Brazil, 1996-2019

Updates Dynamics of Household Land Use and Economic Welfare on the Amazon Frontier, 1996-2005, Rondonia, Brazil, examines household land use and economic welfare of residents living in the highly deforested Amazon basin region of southern Brazil. This release represents the 4th round of data collection which includes primary data from household panel surveys in the core study area, combined with several other sources of data, including cadastral maps matched with satellite imagery to quantify land cover change, spatial data on biophysical factors, markets, and public infrastructure, and secondary data from official sources (such as agricultural census data). Interviews were conducted with respondents residing in the Ouro Preto do Oeste region of the Brazilian state of Rondonia. Survey questions focused on respondent ownership of land lots, years of residency on the lots, property sales, physical characteristics of lots and dwellings, types and quantity of livestock and crops, and use of fertilizers, pesticides, and herbicides. Several questions asked respondents whether they owned various durables, including vehicles, household appliances, tools, and farm equipment. Demographic information includes age of respondent and other household occupants, household size, migration, and education level, as well as information on household income, assets, pensions, and cost of living.

Sampling:   The surveys were administered face-to-face at the lot owner’s residence by pairs of trained interviewers, reporting to field coordinators and project PIs. The responses for the 1996, 2000 and 2005 waves were collected on paper and transcribed daily by the interviewers. The responses for the 2009 and 2019 waves were input directly on tablets by the interviewers on site. The survey teams prioritized interviewing owners of all original lots, those added in prior waves, and a random sample in any new settlements, plus supplemental samples to maintain representativeness by municipality population and increase sample size as budget allowed. This included tracking non-resident lot owners to their new locations if necessary in 2005, 2009 and 2019. Family members who left the original households were also tracked in 2005 and 2009 to the extent that time allowed.
