NLS user since 2000
From the NLSY79 data, I learned that educational differences do not appear to stop young people from cohabiting or moving on to marriage, but that educational difference do appear to be associated with divorce in this cohort. These findings support the notion that marriage is different from cohabitation in perhaps unanticipated ways and/or that cohabitation was not an effective "trial marriage" for this cohort.
The long time span in which respondents are followed in the NLS made it ideal for my study of exits and entries from cohabitation and marriage. The NLSY79 also has education information for both partners in cohabiting and marital unions, making it one of the rare data sets that allow researchers to examine assortative mating longitudinally.
