For this survey, respondents from three counties in the Detroit, Michigan, area were queried about their work, health, marriage and family, finances, political views, religion, and child rearing. With respect to finances, respondent views were elicited on credit card purchases, recording expenditures, and savings and investments. Regarding political views, respondents were questioned about political preferences, presidential values, freedom of speech, nuclear war, and the interest of public officials. Questions also addressed religious beliefs and experiences, including the religiosity of respondents' parents, belief in and relationship with God, the relationship between science and religion, school prayer, divorce, and homosexuality. Additional religious questions -- based on the respondents' religious preference (i.e., Protestant, Catholic, Jew, Other Religion, or No Preference/Agnostic/Atheist Only) -- also were asked, covering topics such as interfaith marriages, religion of friends, and observance of religious holy days. Questions were asked about the views of respondents' religious leaders on issues including drinking, abortion, and test-tube fertilization. Regarding child rearing, views were elicited on issues including religious preference of child(ren) raised, religious training given to child(ren), and frequency of prayer before meals. Background information includes marital status, employment, political orientation, and income. More information about the Detroit Area Studies Project is available on this Web site.

This study is freely available to ICPSR member institutions. Also available as downloadable files. The purpose of the Early Years of Marriage (EYM) Project was to determine ways in which the early development of marriage for Black couples and White couples affect the mental and physical health of spouses, marital stability, long-term marital outcomes, patterns of family life and, for those who divorce, individual adjustment to family disruption. The EYM Project began in 1986 with 373 newlywed couples--174 White couples and 199 Black couples. The marriages were all intra-racial and it was the first marriage for both spouses. Year 1 interviews, which queried the couples on various aspects of married life, began after four to nine months into the marriage. Very few respondents who originally participated in Year 1 of the study refused to participate in subsequent phases of the study. In 1986 (Year 1) and 1988 (Year 3) spouses were interviewed in their homes separately and together, with the interviews conducted by interviewers of the same race. In 1987 (Year 2) and 1989 (Year 4) shorter individual telephone interviews were conducted. In all four years, respondents were queried on a wide variety of topics such as feelings and perceptions of their own family, spouse, in-laws, and their spouse's friends, family planning, how many children they should have, how the children should be reared, childcare, and household roles and responsibilities. A series of questions was asked about reasons for getting married, how satisfying married life was, what, if any, were the special pleasures and good feelings that came from being married, how often arguments and disagreements occurred, main reasons for arguments, and how they were eventually resolved. A series of questions were also asked regarding the mental and physical health of the spouse, job satisfaction, job security, and how the job affected the family. In Year 2 and Year 4 interviews (Parts 2-4), a series of questions regarding separation and divorce were also asked. Demographic variables include race, gender, age, level of education, occupation, income, and religious preference.

The purpose of this data collection was to identify the causes of marital instability throughout the life course. A national sample of married individuals 55 years of age or younger was interviewed by telephone in 1980 and reinterviewed in 1983 and 1988. Spouses were not interviewed. In the first wave of data the investigators focused on female labor force participation, while the next two waves were guided by a life course perspective. An attempt was made to link changes in items such as economic resources, wife's employment, presence of children, marital satisfaction, life goals, and health, to divorce, permanent separation, and other actions intended to dissolve a marriage.

At a time when the range of family structures is becoming more and more diverse, this study permits a close examination of the resulting family compositions and household operations. One adult, the primary respondent, was chosen from each of 13,017 households in the study. In addition to the main interview conducted with the primary respondent, a shorter, self-administered questionnaire was given to the spouse or cohabitating partner. Data were gathered on the composition of families and on the relationship of household members to each other, including marriage, separation, and divorce histories, adoption, child custody arrangements, and stepfamily relations. Respondents were also asked about the quality of their relationships with their parents, children, and in-laws. Information on economic well-being is also provided, including earnings from wages, self-employment income, interest, dividends, investments, pensions, Social Security, public assistance, and child support/alimony.

The National Survey of Families and Households (NSFH) provides data on the family experience in the United States. At a time when the range of family structures is becoming more and more diverse, this study permits a close examination of the resulting family compositions and household operations. Data were gathered on the composition of families, family background, and on the relationship of household members to each other, including marriage, separation, and divorce histories, adoption, child custody arrangements, and stepfamily relations. Respondents were also asked about the quality of their relationships with their parents, children, and in-laws. Information on economic well-being is also provided, including earnings from wages, self-employment income, interest, dividends, investments, pensions, Social Security, public assistance, and child support/alimony. Demographic variables include sex, age, and marital status. For Wave I of the NSFH, which was conducted from March 1987 through May 1988, one adult, the primary respondent, was chosen from each of the households in the sample. In addition to the main interview conducted with the primary respondent, a shorter, self-administered questionnaire was given to the spouse or cohabiting partner of the primary respondent. The NSFH Wave I sample was reinterviewed for the second wave of the survey, which was conducted from 1992 through August of 1994. The Wave II survey included the following components: (1) an interview of all surviving members of the original sample via face-to-face personal interview, (2) a personal interview with the current spouse or cohabiting partner almost identical to the interview with the main respondent, (3) a personal interview with the original spouse or partner of the primary respondent in cases where this relationship had ended, (4) a telephone interview with "focal children" who were originally aged 13-18 in Wave I, (5) a short telephone interview with "focal children" who were originally aged 5-12 in Wave I, (6) short proxy interviews with a surviving spouse or other relative in cases where the original respondent had died or was too ill to interview, and (7) a telephone interview with a randomly-selected parent of the main respondent. Part 1 of this collection contains Wave I data, and Parts 2-16 provide data for Wave II.

Formerly titled Marital Instability Over the Life Course (MIOLC -- ICPSR 3812), the Work and Family Life Study (WFLS) is a follow-up to the MIOLC. The MIOLC examined the causes of marital instability throughout the life course, and contains 6 waves of data collected between 1980 and 2000, which were gathered from married respondents who were between the ages of 18 and 55. The Work and Family Life Study provides data for use in assessing: changes in marital quality between 1980 and 2000; the effects of family-of-origin characteristics and marital history on the physical and psychological health of respondents; and evaluating sample attrition, factors which lead to attrition, and attrition bias. The WFLS collected new cross-sectional information (Part 2 -- Public Use Cross Section, N = 2,189) on married people 55 years of age and younger, using the same sampling procedures and interview questions that were used in the 1980 wave of the MIOLC. The Work and Family Life Study's Public Use Cross Section is the latest addition to the data collections. This new Public Use Cross Section studies the effects of wives' participation in the labor force on marriage and marital instability. Also provided in this collection are the Public Use All Waves (Part 1, N = 2,034) and the Public Use Panel Wave 6 (Part 3, N = 1,031). The Public Use All Waves contains information from Waves I through VI, which were collected in 1980, 1983, 1987, 1992-1994, 1997, and 2000. Among the variables included in all six waves are age, sex, educational attainment, marital status and history, attitude toward divorce, number of children, religious affiliation, and income level. The Public Use Panel Wave 6 contains data on persons who only responded to wave 6 of the study. Unique to this data collection, the Public Use Comparison file (Part 4, N = 11,741) contains information on respondents who would have been between the ages of 18 and 55 in 1980, married, and living with their spouse. These data evaluate potential bias from sample attrition in the panel study. The Comparison Sample is a special purpose sample and does not generalize to a normally defined population of ever married persons.
