This study, DIFFUSION OF SUSTAINABLE AGRICULTURE IN THE AMAZON [BRAZIL]: A PANEL DATABASE, 1996-2000, is no longer current. Please see DYNAMICS OF HOUSEHOLD LAND USE AND ECONOMIC WELFARE ON THE AMAZON FRONTIER, 1996-2005, RONDONIA, BRAZIL (ICPSR 25322), which includes a third round of panel data (2005), as well as edits and changes to the previous years (1996 and 2000).
This study gathered farm-level panel data in Ouro Preto do Oeste, Rondonia, Brazil, to determine the relationship between household decisions and land use for Amazonian households. This project was initiated in August 1996 when a stratified random sample of 171 farmers in Ouro Preto do Oeste was selected along with 25 households that participate in the Association of Alternative Producers (APA) to investigate the decisions of farmers using slash-and-burn agriculture and others using sustainable methods of farming. The survey questions consisted of inquiries about the household (including age, education level, farming experience, and number of farm animals owned), lot characteristics (including size and division between pasture, forest, agriculture, and agroforestry), harvest of market and subsistence crops, agricultural and other forms of income, and the use of agroforestry and major influences determining farming techniques. Questions about income derived from agriculture provided information about the harvest of all perennial and annual crops, milk harvest and meat harvest, the amount of each item that was sold, and at what price.
Iowa Youth and Families Project, 1989-1992 (ICPSR 26721)
This data collection contains the first four waves of the Iowa Youth and Families Project (IYFP), conducted in 1989, 1990, 1991, and 1992. The Iowa Youth and Families Project was developed from an initial sample of 451 7th graders from two-parent families in rural Iowa. The study was merged with the Iowa Single Parent Project (ISPP) to form the Iowa Family Transitions Project in 1994, when the target youth were seniors in high school. Survey data were collected from the target child (7th grader), a sibling within four years of age of the target child, and both parents. Field interviewers visited families at their homes on several occasions to administer questionnaires and videotape interaction tasks including family discussion tasks, family problem-solving tasks, sibling interaction tasks, and marital interaction tasks.
The Household Data files contain information about the family's financial situation, involvement in farming, and demographic information about household members.
The Parent and the Child Survey Data files contain responses to survey questions about the quality and stability of family relationships, emotional, physical, and behavioral problems of individual family members, parent-child conflict, family problem-solving skills, social and financial support from outside the home, traumatic life experiences, alcohol, drug, and tobacco use, and opinions on topics such as abortion, parenting, and gender roles. In addition, the Child Survey Data files include responses collected from the target child and his or her sibling in the study about experiences with puberty, dating, sexual activity, and risk-taking behavior.
The Problem-Solving Data files contain survey data collected from respondents about the family interactions tasks.
The Observational Data files contain the interviewers' observations collected during these tasks.
Demographic variables include sex, age, employment status, occupation, income, home ownership, religious preference, frequency of religious attendance, as well as the ages and sex of all household members and their relationship to the head of household. Demographic information collected on the parents also includes their birth order within their family, the ages and political philosophy of their parents, the sex, age, education level, and occupation of their siblings, and the country of origin of their ancestors.
