09:00 | Early Parenthood and Inequalities in Family and Work Trajectories.Experiences of women and men in urban Mexico SPEAKER: unknown ABSTRACT. During the second half of the twentieth century, the expansion of the educational system in Mexico has achieved an important goal: children and youth increasingly attend and remain in school. Gender inequalities in school attendance and attainment have disappeared but inequalities between socioeconomic sectors remain. Most students only attain low middle education and access to higher levels continues to be restricted to higher socioeconomic sectors. Growing education levels and a rapid urbanization process are related to an important increase in female labor force participation. However, female participation remains relatively low and labor markets have been growingly unstable, precarious and segmented, and better job opportunities greatly differ by education levels. At the same time, the fertility transition has taken place in Mexico. Fami-ly size has been notably reduced. In spite of this and other profound transfor-mations related to family values, patterns during the first stages of family for-mation have shown only minor changes in the population as a whole. Most women enter a conjugal union and have the first child at early ages. Mothers aged less than 20 years give birth to one out of every five births. Only a small minority of women delay their marriage and childbearing period. These different behaviors are strongly associated to education inequalities and unequal labor perspectives. Early ages at birth of first child are associated to economic and social disadvantages. Maternity at early ages causes low education and participation in the labor market. When young mothers work, they have more precarious jobs and lower incomes than older mothers. Early timing of fertility can act as a trigger of accumulation of disadvantages in later stages of life. Nevertheless, having an early birth is also a probable consequence of poverty because of previous disadvantages young women face before becoming pregnant. It has been pointed out that the opportunities of Mexican women who become pregnant as teenagers to receive education and progress toward rewarding and fulfilling jobs are limited, regardless of their fertility decisions. Also, among Mexican young women, mainly from the poorest sectors, the desire to get pregnant often results from the lack of education and work opportunities. Teen age pregnancy is perceived by the Mexican government as a popu-lation problem that widens social and gender gaps. In order to prevent these preg-nancies, a national program which involves the Health, Education and Economy Ministries has been recently implemented (ENAPEA, 2015). One of its goals is to reduce teenage fertility rate (70 per thousand) in half. However, a complete suc-cess of the program is not expected, given the lack of scientific knowledge on sev-eral issues, mainly the long term effects of early pregnancies and the experience of young boys who are often the teenage mothers’ couples. Most studies on teenage fertility that show the association with economic and social disadvantages are cross-sectional or follow ups for short periods of time. In Mexico, it is unknown if early mothers catch up latter on in other spheres of their lives and end having similar conditions as women of the same social sec-tor who started their childbearing period at latter ages or remain childless. Mexican males’ reproductive patterns have been scarcely studied and early fatherhood has not been a matter of concern. However, given the male bead winner traditional role, adopting the responsibility of a child and a family at early ages might also affect their family and work life paths. In this paper, our objective is to study family and work trajectories of in-dividuals and determine if early transitions to parenthood are associated to adverse consequences in later stages of life that exacerbate previous socioeconomic inequalities. We study women's as well as men's trajectories, given our interest in both experiences and in gender inequalities. The main contributions of the paper are the use of a life course perspec-tive to observe long term trends; the simultaneous analysis of the interwoven school, work, marital and reproductive trajectories; the evaluation of inequalities by social strata, and the inclusion of men’s as well as female’s experiences. 1.1 Methodology and data source A Multichannel Sequence Analysis is applied in order to simultaneously study the trajectories in the family and work domains. A distances matrix is calculated ap-plying optimal matching analysis. In order to group the life paths, an agglomera-tive hierarchical clustering of the distances matrix data is computed; the Average Silhouette Width is used to define the number of groups. We analyze school, work, marital and reproductive dimensions. States are in school and out of school for the first dimension. Work states are at home, self employed (mainly associated to informal jobs) and salaried work (associated to more formal and stable jobs). In the marriage dimension, states are single, in first, second and third or more marital union (marriage or cohabitation) and previously married. In the reproductive dimension states are the number of children ever born that goes from zero to 5 or more. To explore the social composition of the groups of the life paths defined by the cluster analysis, multiple correspondence analyses is carried out for women and men separately; besides the cluster groups, variables are birth cohort, social strata and having had an early birth. The data source is the Retrospective Demographic Survey (Eder 2011), carried out in urban areas of Mexico. We use annual data on school, work, and family life histories from ages 12 to 41 of 888 women and 851 men of two birth cohorts born in 1951-1953 and 1966-1969. As indicator of the social strata, we use a variable created with data on education and economic features of parents of the interviewees at age 15. This variable is particularly relevant given the profound social inequalities that charac-terize de Mexican society; it reflects the socioeconomic conditions of the parents’ household when the individual was about to start his family and work trajectories. Because of the traditional gender roles, we analyze women and men’s work and family experiences separately. Besides, nuptiality and fertility timing among men take place at later ages than among women and we are especially interested in the effects of the social timing. We consider an early motherhood when occurred before age 18 and an early fatherhood when occurred before age 20. At age 18, young people attain the age of majority, are supposed to finish the upper secondary school which is compulsory and are legally able to have full time jobs. As mean differences by sex in age at first marriage and first birth are around two years, we suppose an early birth for males occurs before reaching the 20 years of age.

09:25 | Differences in Health between East and West Germans: The "Long Arm of Childhood" under Divergent Political Regimes in Germany SPEAKER: Katharina Loter ABSTRACT. The aim of our study is to investigate the “long arm of childhood” under two divergent political regimes in Germany. Children of the former socialist German Democratic Republic (GDR) grew up in a regime with full-time working mothers and around the clock child care services – in a regime that differed significantly from the German Federal Republic (FRG, also West Germany). GDR, year 1980: Almost 60% children aged 0-3 attend nurseries and more than 90% children aged 3-6 attend all-day kindergartens. In contrast, the respective percentages in the FRG are 1% for nurseries and 65% for predominantly part-time kindergartens. Thus, a great majority of children born and raised in the GDR experienced “equal” educational and nutritional conditions during early childhood regarded as a critical period of development, irrespective of their families’ socio-economic situation. Within few years after the German unification health care in East Germany came up to the level of West Germany, nonetheless, for the “former children of the GDR” early childhood influences may continue to affect their adult health in a specific way. Our research question is: Does the childhood experience under a socialist regime play a role in explaining health at subsequent stages of the life course? First, we hypothesize that spending childhood in the GDR, unlike in the FRG, might have an adverse long-term effect on health. Second, we assume that “equal” GDR childhood conditions might attenuate the long-term impact of parental socio-economic status on adult health. To examine these hypotheses we use data from the German Socio-Economic Panel (SOEP) for birth cohorts 1950-1980 and apply latent growth curve analyses. Our preliminary results provide evidence of health disparities according to the kind of socialization. Further, we observe different patterns in the social health gradient for East and West Germans. |
09:50 | Childbearing after Union Dissolution: Does the Sequence of Union Matter? SPEAKER: Sergi Vidal ABSTRACT. Research has examined the recent patterns of childbearing out-of-wedlock as well as the associations between childbearing and union transitions. Less systematic has been research on deciphering fertility patterns after union dissolution. This is limiting since life courses are increasingly diverse regarding partnership and family careers, and part of the well-documented changing fertility patterns across union types may be due to factors that lead individuals to dissolve unions and re-partner. We address this gap in knowledge by theorizing and examining how childbearing evolves after union dissolution. For the empirical analysis, we use hazard regression for first-, second- and third-order childbearing episodes of women aged 16 to 40 from the panel study Household, Income and Labor dynamics in Australia. Preliminary results from parity-specific models show that fertility rates are the highest among first-order marital unions. We also find that subsequent unions (to the first one) have increased first-order childbearing rates. Our study contributes to the understanding of contemporary fertility patterns, by shedding light on fertility variations across partnership life courses. Further work will include, among others, the simultaneous estimation of childbearing and union transitions to assess the effect of unobserved factors that commonly affect both processes. |
09:00 | Relational sequence networks as a tool for studying gendered mobility patterns SPEAKER: Klaus Hamberger ABSTRACT. This paper uses relational sequence networks to study the gendered differences of migration biographies. Starting from an integrated model of kinship and migration relations as parts of a single bi-modal network of individuals and events, sequence networks are constructed by classifying mobility events according to the social (kinship or other) relation between the individuals they link together (e.g. as migrants and hosts). Itineraries thus are conceived of as walks in a space of relational positions. Using data from 508 migration biographies collected in South-east Togo between 2010 and 2015, it is shown that male and female trajectories do not so much differ in their degree of mobility or their geographical orientation, as in the topology of the social spaces they traverse and in the structure of the social sequences they trace. While both rest on a basic kinship axis (linking an “internal” parent pole and an “external” extended-kinship pole), male networks tend to evolve through a succession of multiple but structurally isolated non-kinship links, whereas female networks develop into complex and integrated multifocal networks sewn together by marital and affinal ties. Data have been analyzed with the open source software Puck 2.2., which implements the model presented in the paper. |
09:25 | Childhood co-residence structures and home-leaving: A combination of survival and sequence analyses SPEAKER: Florence Rossignon ABSTRACT. The aim of this study is to examine whether the co-residence structures in which young adults grew up is likely to affect their propensity of leaving the parental home. The empirical research was based on the LIVES Cohort study, a panel survey that started in autumn 2013 in Switzerland. Two longitudinal statistical methods were used as complementary approaches. First, sequence and cluster analyses were conducted to identify typical trajectories of childhood co-residence structure. Second, event history analysis was used to estimate whether these aforementioned structures influence home-leaving. Analyses show that it is not only the occurrence of an event that increases the risk of experiencing another event, but also the order in which various states occurred. What is more, it seems that two features have a significant influence on the departure from the parental home, which are the co-residence structures and the arrival or departure of siblings from the parental home. |
09:50 | A New Tool for Old Questions: The Sequence-Analysis Multistate Model to Study Relationships Between Time-Varying Covariates and Trajectories. SPEAKER: unknown ABSTRACT. The relationship between processes and time-varying covariates is of central theoretical interest in many social sciences research questions. On the one hand, event history analysis has been the method of choice to study these relationships. However, it is limited to outcomes that can meaningfully be specified as simple instantaneous events or transitions. On the other hand, sequence analysis (SA) has made increasing inroads into the social sciences to analyze trajectories as holistic ``process outcomes''. However, it does not allow for studying their relationship with time-varying covariates. We propose the sequence-analysis multistate model (SAMM) that combine the advantages of both approaches. SAMM models the relationship between time-varying covariates and trajectories specified as processes outcomes that unfold over time. it proceeds in two steps. First, we use an adapted sequence analysis to identify typical sequencing and spacing between main transitions in trajectories. Second, we adapt multistate models to estimate the chances to follow each kind of the identified typical sequence. The usefulness of SAMM is illustrated with an example from life course sociology on how 1) time-varying family status is associated with women's employment trajectories in East and West Germany, and 2) how the German reunification affected these trajectories in the two sub-societies. |
10:45 | Physical occupational exposures and healthy life expectancy in a French occupational cohort SPEAKER: unknown ABSTRACT. To examine the relationships of strenuous and hazardous working conditions and night work with healthy life expectancy (HLE). The sample contained male gas and electricity workers from the French GAZEL cohort (n=13654). Six measures of physical working conditions were examined: Self-reports from 1989 and 1990 of ergonomic strain, physical danger, night work and perceived physical strain; company records of workplace accidents and a job-exposure matrix of chemical exposures. Partial HLEs (age 50–75) relating to 1) self-rated health and 2) chronic health conditions, obtained from annual questionnaires (1989–2014) and company records, were estimated using the multi-state life table method and microsimulation. The analyses were adjusted for social class and occupational grade. Participants who reported more physically demanding and dangerous work did not have shorter partial life expectancy but had shorter healthy life expectancies in terms of both chronic illness and self-rated health. No differences were ob-served in relation to night shift work. Strenuous and hazardous work may con-tribute to ill health in later life, which has implications for individuals’ quality of life as well as healthcare use and labour market participation. |
11:10 | Taking Turns or Halving It All: Care Strategies of Dual-Caring Couples SPEAKER: Helen Eriksson ABSTRACT. The birth of a child induces parents to substitute family work for paid work. As responses to child care time demands remain remarkably gendered, division of child care in relation to parents’ work is key to understanding reproduction of gender inequality in both the family and the labor market. This study conceptualizes a ‘care strategy’ as a trajectory of time allocations by mothers and fathers to primary child care, i.e., care that requires absence from work, over the child’s early years. It makes use of detailed data on claims for parental leave and sequence analysis to identify care strategies. Results show that half of all Swedish couples realize dual-caring strategies in which each parent serves as primary caregiver for substantial periods of the child’s early life. Despite a uniquely flexible parental leave system that allows egalitarian couples to share care on a daily basis, the dominant dual-caring strategy consists of ‘taking turns’ in serving as primary caregiver where the mother takes leave to care for an initial period, followed by a period of solo-father care. One fourth of dual-caring couples, about 10 percent of all couples, use a ‘halving it all’ strategy in which primary care is shared in every point in time. |
11:35 | Family structures and the organization of care for children in Italy. Sequences of time use by caregivers and activity SPEAKER: Tiziana Nazio ABSTRACT. Using time diary data from Italy (time use survey 2008-09), on a sample of 5200 households with children younger than 14 years of age, this paper assesses the amount of differences (in any) in the time mothers and fathers devote to unpaid childcare in differently shaped family structures (marital or cohabiting union, single parent and blended family), and how in turn family structure reflects in children’s time use (addressing several activities from children’s time diaries, as well as the overall amount of time children spend in presence of their parents or other caregivers). Time-use data obtained from daily diaries allow examining both the overall amounts spent on activities by day and, through sequence analysis, the patterns though which parents and children in different family structures engage in specific activities. [NOTE: This is a very preliminary draft with pilot analyses. Further refinements will include: (1) increase in the sample size by addition of the 2002-03 time use survey and a focus on weekdays (harmonization across time use categories has already performed); (2) from the parental diaries: sequence analysis of routine and engaged childcare, work and personal activities; (3) from children’s diaries: further distinction of institutionalized time (in school or extra curricular activities) from “time with others” and a clearer partition of “time alone” from sleeping time; (3) produce better representation of sequence index plots, with pos-sible streamlining of the space state; (4) if possible, statistical testing of the differ-ences across sequences in time use by family type (Liao and Fasang 2015, Jalovaara and Fasang 2015)]. |
10:45 | Missingness and truncation in sequence data: A non-self-identical missing state SPEAKER: Brendan Halpin ABSTRACT. Missingness in sequence data is a problem that has not received a great deal of attention. Two approaches are suggested in the literature: treating missingness as a separate state, and multiple imputation. In this paper I propose a new concept: a non-self-identical missing state, where missing/missing combinations are treated as mismatches. I apply this to both normal missingness (gaps) and truncation of sequences. Tests with simulated and real data show it works well with normal missingness, but is not a big improvement on OM's default behaviour with sequences of unequal length. |
11:10 | Normalization of Distance and Similarity in Sequence Analysis SPEAKER: unknown ABSTRACT. We explore the relations between the notion of distance and a feature set based concept of similarity and show that this concept of similarity has a spatial interpretation that is complementary to distance: it is interpreted as ``direction''. Furthermore, we show how proper normalization leads to distances that can be directly interpreted as dissimilarity: closeness in normalized space implies and is implied by similarity of the same objects while remoteness implies and is implied by dissimilarity. Finally, we show how, in research into de-standardization of the life course, properly normalizing may drastically and unequivocally change our interpretation of inter-cohortal distances. |
11:35 | Do State Policies Generate Different Life Courses? An Empirical Study of the Case of Divided Germany via a Statistical Assessment SPEAKER: unknown ABSTRACT. In this paper, we use the example of the German division and reunification to assess how different state policies affect longitudinal employment and family trajectories from early adulthood to midlife. Statistically assessing differences in longitudinal life courses is difficult because they are far more complex than simple random variables measured at one point in time. We propose a new medoid-based method for formally assessing the difference between sets of life course sequences. Our paper thereby seeks to make both a substantive and a methodological contribution. First, we provide new insights on the formative impact of the East and West German state policies on life courses in divided Germany and their convergence after the reunification. Second, we demonstrate the added value of the medoid-based approach for statistical assessment of differences in sets of sequence data and propose a Bayesian Information Criterion (BIC) and the Likelihood Ratio Test (LRT) statistic in the context of sequence comparisons. To evaluate the proposed methods we present an application to the German case study using retrospective life course data from the German National Education Panel Study (NEPS) as well as a simulation study. We conclude that the proposed test statistics for sequence comparison have many potential applications in life course sociology and beyond. |
13:30 | Intergenerational Patterns of Family Formation in East and West Germany SPEAKER: unknown ABSTRACT. Why is intergenerational transmission of family formation weaker in some country contexts than in others? This paper employs the historically unique situation of the German division to study country context effects on intergenerational regularities in family formation. We use the German Socio-Economic Panel (SOEP) to analyze the longitudinal family formation trajectories from age 15-35 of children born 1953-1978 and their mothers. Findings show that East German mother-child family formation trajectories are more dissimilar than West German mother-child family formation trajectories. Further, East German mother-child dyads are more likely to be categorized as patterns of intergenerational contrast, whereas West German mother-child dyads are more likely to display strong transmission. To account for these differences in intergenerational transmission of family formation between East and West Germany, we propose to combine multichannel sequence analysis, multinomial logistic modeling and decomposition methods for nonlinear probability models. This methodological approach enables us to show that differences in parental education and children’s educational mobility in East and West Germany mediate the strength of intergenerational transmission and contribute to explaining differences in intergenerational patterns of family formation in the two contexts. We conclude that the proposed approach is promising to disentangle cross-national differences in intergenerational regularities in family formation. |
13:55 | Enduring contexts. Persistent segregation by affluence through the life course SPEAKER: Maren Toft ABSTRACT. This paper adheres to calls for incorporating time and place as important aspects in shaping contemporary inequality. Drawing on Sharkey’s (2013) concept of ‘contextual mobility’– understood as the social composition of one’s neighbourhood over time – this paper seeks to investigate enduring structures of context in the Oslo region by following three complete birth cohorts left their parental home in 1989 and measure their social surroundings onwards until adult-hood in 2012. The context of each individual is recorded annually with particular emphasis on the extremes in the social environments, i.e. the affluent versus the deprived areas. Utilizing sequencing and clustering techniques, the analysis shows that lasting exposure to reoccurring contexts characterize neighbourhood biographies of both dense advantage and disadvantage – indicative of vastly limited life experiences. Moreover, those who experience a neighbourhood career of dense advantage are also more likely to have privileged class origins and to obtain access into the upper class in adulthood and the inverse relationship characterizes the career of neighbourhood disadvantage. Those who are surrounded by persistent advantage are, however, the most isolated geographically and thus the more likely to be socially acquainted, although all neighbourhood typologies become more clustered in the region over time. I argue that an understanding of how spatially mediated contexts unfold throughout the life course hints to processes of class structuration and thus makes for an important addition to insight into present-day inequality. |
13:30 | Trajectories of vulnerability: a multi-dimensional approach SPEAKER: unknown ABSTRACT. Our paper explores vulnerable trajectories across three life course domains: employment activity, cohabitation and health status. We embrace a compre-hensive point of view applying multichannel sequence analysis to a sample of about 1250 residents of the Canton de Vaud considering the period from age 1 to 40. Our results confirm the diffusion of the effects of vulnerable statuses across life course domains. |
13:55 | Multiphase Optimal Matching : An Application to Participation Careers in Pâtissiers' Competitions SPEAKER: Thomas Collas ABSTRACT. The contribution aims to discuss the use of Optimal matching analysis (OMA) to compare sequences defined by two or more idiosyncratic phases, called multiphase sequences. It relies on a study of individual careers defined as successions of rankings in pâtissiers’ competitions in France (N=1258). First, four properties of multiphase sequences will be set out. Then, an application of OMA to a set of two-phase sequences will be detailed. Lastly, questions related to multiphase OMA will be raised. |
