Single-parent households and children's educational achievement: A state-level analysis.

Although many studies have examined associations between family structure and children's educational achievement at the individual level, few studies have considered how the increase in single-parent households may have affected children's educational achievement at the population level. We examined changes in the percentage of children living with single parents between 1990 and 2011 and state mathematics and reading scores on the National Assessment of Educational Progress. Regression models with state and year fixed effects revealed that changes in the percentage of children living with single parents were not associated with test scores. Increases in maternal education, however, were associated with improvements in children's test scores during this period. These results do not support the notion that increases in single parenthood have had serious consequences for U.S. children's school achievement.

Reassessing the Link between Women's Premarital Cohabitation and Marital Quality.

Using data from 2,898 women from the National Longitudinal Survey of Youth-1979, we employ a novel method to examine two perspectives, social selection and the experience of cohabitation, commonly used to explain the negative relationship outcomes cohabiting women report. Results reveal cohabitation is negatively related to marital happiness and communication and positively related to conflict. As in previous research, selection mechanisms appear to increase the odds of cohabitation while decreasing marital happiness. A closer examination of the problem also reveals a negative effect of the experience of cohabitation. This paper's primary contributions are the ability to model selection and experience in the same model and evidence of a robust effect of cohabitation on marital quality. These results underscore the complex pathways between union formation, family structure and marital outcomes.
