description: 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 19 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 19 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.

a random-digit dialing cluster technique. Data were weighted to adjust for underrepresentation in metropolitan areas.
