This study, which updates Dynamics of Household Land Use and Economic Welfare on the Amazon Frontier, 1996-2005, Rondonia, Brazil (ICPSR 25322), examines household land use and economic welfare of residents living in the highly deforested Amazon basin region of southern Brazil. This release represents the fourth 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.

ICPSR study 34905 incorporates data from the most recent survey wave, as well as all previous waves. There are two previous releases of this survey: ICPSR 3948 Diffusion of Sustainable Agriculture in the Amazon [Brazil]: A Panel Database, 1996-2000, and ICPSR 25322 Dynamics of Household Land Use and Economic Welfare on the Amazon Frontier, 1996-2005, Rondonia, Brazil.

Each of the surveys administered in the four waves of this panel were collected via a stratified random sample. In 2005 and 2009, households were added to the sample by randomly sampling lots in new settlements in the study area and adding a supplementary sample of lots designed to maintain the size and representativeness of the sample. For additional information on sampling, please see the Original P.I. Documentation section of the ICPSR Codebook.
