Assessing the impact of timing errors in sequence analysis
The standard practice in sequence analysis is to regard sequences as exact and measured without error. Transition timing is a common source of sequence measurement error in social research. In this paper, we propose a method for conducting Monte Carlo simulations of transition timing errors to assess the robustness of sequence analysis outcomes against such timing errors. The method consists in repeating multiple times the analyses with updated s…
Geneva. An Urban Sociodemographic Database
The Geneva databases are a data resource covering the period 1800–1880 for the city of Geneva, and occasionally the canton of Geneva. The research team adopted an alphabetical sampling approach, collecting data on individuals whose surname begins with the letter B. The individuals and households belonging to this sample in six population censuses between 1816 and 1843 were digitised and linked. A second database collected marriage and divorce rec…
Strategies for Multidomain Sequence Analysis in Social Research
Multidomain/multichannel sequence analysis has become widely used in social science research to uncover the underlying relationships between two or more observed trajectories in parallel. For example, life-course researchers use multidomain sequence analysis to study the parallel unfolding of multiple life-course domains. In this article, the authors conduct a critical review of the approaches most used in multidomain sequence analysis. The paral…
Measuring the Nature of Individual Sequences
This study reviews and compares indicators that can serve to characterize numerically the nature of state sequences. It also introduces several new indicators. Alongside basic measures such as the length, the number of visited distinct states, and the number of state changes, we shall consider composite measures such as turbulence and the complexity index, and measures that take account of the nature (e.g., positive vs. negative or ranking) of th…
Sequence analysis: Its past, present, and future
This article marks the occasion of Social Science Research's 50th anniversary by reflecting on the progress of sequence analysis (SA) since its introduction into the social sciences four decades ago, with focuses on the developments of SA thus far in the social sciences and on its potential future directions. The application of SA in the social sciences, especially in life course research, has mushroomed in the last decade and a half. Using a lif…
Sequence Analysis and Related Approaches: Innovative Methods and Applications
This open access book provides innovative methods and original applications of sequence analysis (SA) and related methods for analysing longitudinal data describing life trajectories such as professional careers, family paths, the succession of health statuses, or the time use. The applications as well as the methodological contributions proposed in this book pay special attention to the combined use of SA and other methods for longitudinal data …

Changes in the Order of Family Life Events in 20th-Century Europe: A Cross-Regional Perspective
This article analyzes the evolution of the sequencing of family life events in Europe during the second half of the 20th century using individual data from the European Social Survey and from the Generation and Gender Program. Considering the four events ‘leaving the parental home‘, ‘first cohabiting union‘, ‘first marriage‘, and ‘first parenthood‘, we hypothesize a transition from a traditional standard event order characterized by a high degree…
Parental leave within the broader employment trajectory: What can we learn from administrative records
Purpose The purpose of this paper is to present an analysis of parental leave use and long-term employment trajectories of parents in Luxembourg based on anonymous administrative records. This is the first systematic analysis of parental leave take-up rates and return rates for Luxembourg using a large and reliable data set. Design/methodology/approach The authors use highly detailed administrative data to calculate take-up and return rates for p…
What Matters in Differences Between Life Trajectories: A Comparative Review of Sequence Dissimilarity Measures
This is a comparative study of the multiple ways of measuring dissimilarities between state sequences. The originality of the study is the focus put on the differences between sequences that are sociologically important when studying life courses such as family life trajectories or professional careers. These differences essentially concern the sequencing (the order in which successive states appear), the timing and the duration of the spells in …
Analyzing and Visualizing State Sequences in R with TraMineR
This article describes the many capabilities offered by the TraMineR toolbox for categorical sequence data. It focuses more specifically on the analysis and rendering of state sequences. Addressed features include the description of sets of sequences by means of transversal aggregated views, the computation of longitudinal characteristics of individual sequences and the measure of pairwise dissimilarities. Special emphasis is put on the multiple …
Discrepancy Analysis of State Sequences
In this article, the authors define a methodological framework for analyzing the relationship between state sequences and covariates. Inspired by the principles of analysis of variance, this approach looks at how the covariates explain the discrepancy of the sequences. The authors use the pairwise dissimilarities between sequences to determine the discrepancy, which makes it possible to develop a series of statistical significance-based analysis …

The Start of the Sexual Transition in Mali: Risks and Opportunities
Analysis of data from a questionnaire survey of 2,000 young Malians undertaken by the authors in 2002 demonstrates that, even in underprivileged urban and rural populations, changes in sexual behavior are emerging. Among women, first sex and motherhood are taking place slightly later, and a minority is now dissociating sexuality and procreation. Our data confirm the considerable impact of female education on this transition. Girls’ sexual activit…
Les solitudes urbaines. Structures et parcours dans la Genève des années 1816-1843
Ce papier revisite le thème des solitudes dans les structures et le fonctionnement social des villes préindustrielles à partir d’une étude de cas, celui de Genève entre 1816 et 1843. En empruntant à des traditions de recherche issues de la démographie historique, de l’histoire de la famille, de l’histoire sociale et histoire des femmes, une typologie des formes de solitude est proposée. Appliquée aux recensements genevois dans une perspective tra…
Maximisation de l'association par regroupement de lignes ou de colonnes d'un tableau croisé
The strength of association between the row and column variables in a crosstable varies with the level of aggregation of each variable. In many settings such as the simultaneous discretization of two variables, it is useful to determine the aggregation level that maximizes the association. The main association measures with respect to aggregation of rows and columns are studied and permits a heuristic algorithm to (quasi-)maximize the association…

Social status, types of family interaction and educational styles
It is A well-established fact that families vary quite widely in their educational practices. In the past twenty years a certain number of studies on socialization have revealed a clear relation between the socioeconomic status of the parents and their educational style. Kohn (1977), for example, has shown that the emphasis parents put on discipline and immediate conformity is more pronounced in lower-class groups, whereas middle class groups val…
