“…The similarity between two sequences is systematically determined by calculating the total “costs” of turning one sequence into another (Brzinsky-Fay and Kohler 2010). We use transition rates (probability) between two states as the transformation (substitution) costs (Halpin 2014), yielding a dissimilarity matrix for every two pairs of sequences in the data. In the third step, we reduce the large number of sequences into a finite number of substantively distinct clusters, using the dissimilarity matrix obtained in the second step.…”

Women’s Short-Term Employment Trajectories Following Birth: Patterns, Determinants, and Variations by Race/Ethnicity and Nativity

Despite a large literature documenting the impact of childbearing on women's wages, less understanding exists of the actual employment trajectories that mothers take and the circumstances surrounding different paths. We use sequence analysis to chart the entire employment trajectory for a diverse sample of U.S. women by race/ethnicity and nativity in the first year following childbirth. Using data from the 1996-2008 panels of the Survey of Income and Program Participation and sample selection models, we find that women employed before childbirth show a high degree of labor market continuity. However, a notable share of them (24 %) took less stable paths by dropping out or scaling back work. In addition, mothers' attachment to the labor force is simultaneously supported by personal endowments and family resources yet constrained by economic hardship and job characteristics. Moreover, mothers' employment patterns differ by race/ethnicity and nativity. Nonwhite women (blacks, Hispanics, and Asians) who were employed before childbirth exhibited greater labor market continuation than white women. For immigrant women, those with a shorter length of residence were more likely to curtail employment than native-born women, but those with longer duration of residence show greater labor force attachment. We discuss the implications of these findings for income inequality and public policy.

“…Comparing each sequence to all other sequences results in a matrix that quantifies the distances for each pair of individual sequences in the sample and that can then be used to group sequences into clusters based on cluster analyses ('Ward's linkage'). To determine the most appropriate number of clusters, for both men and women, we compare solutions between 4 and 10 clusters, including commonly used quality measures: Calinski-Harabasz and Duda-Hart stopping rules (Duda et al, 2012;Halpin, 2017). We also look at the resulting cluster sizes and evaluate each cluster solution in terms of its content validity, and whether a higher cluster solution adds another cluster of interest.…”

“…Importantly, to address potential reverse causality (poor health leading to particular trajectories), all regression models exclude participants who reported that they were diagnosed with depression before the age of 30 (8 men and 18 women). All calculations and figures are based on Stata 13 with the Sadi extension for sequence analysis (Halpin, 2017).…”

Objectives: The paper identifies types of work-family trajectories of men and women and investigates their links with depression at older age. Method: We use data from the Heinz Nixdorf Recall study, with retrospective information on employment histories and parenthood between age 20 and 50 (1482 men and 1537 women, born between 1925 and 1955). We apply sequence analysis and group trajectories into six clusters for each gender. We test their association with two alternative measures of depression: self-reported depressive symptoms and intake of antidepressant medication. Multivariate models exclude participants with early life depression and adjust for age, marital status, education, and income. Results: We find clear differences of work-family trajectories between men and women, where women's trajectories are generally more diverse, and include family leaves and returns into full or part-time work. For men, work-family trajectories are neither related to depressive symptoms nor to medication intake. In contrast, women who returned into full-time work after family leave show more depression than those who return part-time, both in terms of depressive symptoms and intake of antidepressant medication. Conclusion: Our findings show gender differences in terms of work-family trajectories and their health-related consequences. In particular, findings suggest that mothers who return to full-time work are a vulnerable group for depression at older age and should be the focus of further research attention.

“…Finally, we used the clusters as the categorical dependent variable in a multinomial logistic regression to understand how certain individual characteristics influence the probability of separated individuals to belong to the identified clusters. The sequence analysis, OM, and cluster analysis were performed using the SADI package in STATA (Halpin 2017), which relies on the SQ package (Brzinsky-Fay, Kohler, and Luniak 2006) to calculate the descriptive statistics and prepare graphs.…”

Union dissolution and housing trajectories in Britain

BACKGROUND A growing body of literature shows that divorce and separation have negative consequences for individuals' residential mobility and housing conditions. Yet, no study to date has examined housing trajectories of separated individuals. OBJECTIVE We investigate housing trajectories of separated men and women using longitudinal data from Britain. METHODS We apply sequence analysis to data from 18 waves of the British Household Panel Survey (1991-2008). We use time since separation as the 'clock' in our analysis and examine the sensitivity of the results to attrition, the length of the observation window, and the choice of classification criteria. RESULTS We identify five types of housing trajectories among separated individuals: 'owner stayers,' 'owner movers,' 'social rent stayers,' 'social rent movers,' and 'private renters.' Men are more likely to stay in homeownership, whereas women are more likely to stay in social housing. There is an expected educational gradient: Highly educated individuals are likely to remain homeowners, whereas people with low educational level have a high propensity to stay in or to move to social housing. Overall, this study shows that some individuals can afford homeownership after separation, and that social housing offers a safety net for the most vulnerable population subgroups (low-educated women with children). However, a significant group of separated individuals is unable to afford homeownership in a country where homeownership is still the norm. http://www.demographic-research.org CONTRIBUTION This study shows that separation has long-term consequences for individuals' housing conditions and that post-separation housing trajectories are significantly shaped by individuals' socioeconomic characteristics.
