Considered as a key index of social stratification, social homogamy (i.e. resemblance of partners within couples) has been used by a sociological research stream to put to the test modernisation and industrialisation theories, which hold that development comes together with a less rigid class structure and a weaker role of kinship in individual destinies. This article applies for the first time this reasoning at the sub-national scale using data regarding 149 regions of 26 European countries in 2014-2016 (European Labour Force Surveys, Eurostat). We show that educational and socioeconomic homogamy get weaker when disposable income per inhabitant increases, but that it stabilises beyond a level corresponding to the average income of studied regions. This relation also holds between regions belonging to a given country once the stronger homogamy of capitals and large metropolises is controlled for.

It has often been argued that women’s employment growth is a factor that contributes to the increase in inequalities between households due, in particular, to an alleged reinforcement of social homogamy. In contrast to this idea, an accounting approach to inequality decomposition, based on Insee’s Labour Force surveys (enquêtes Emploi) shows that wage inequalities between couples aged 30 to 59 remained stable between 1982 and 2014 in France, whereas they would have increased had women’s employment rate not risen. This overall stability results from two converse developments, which are themselves linked to the strong growth in women’s employment over this period: a fall in wage inequality between women and an increase in the correlation of partners’ wages within couples. However, the almost uniform increase in women’s employment rate, regardless of their partner’s wage level, has limited the increase in the correlation of partners’ wages and prevented an increase in wage inequalities between couples.

In France today, women are more highly educated than men. This has affected first union formation and the traditional tendency – known as female hypergamy – for women to form unions with men who are more educated than themselves. Using data from the Family History survey (Étude de l’histoire familiale, INSEE-INED, 1999), Milan Bouchet-Valat analyses the educational characteristics of partners in a first union and the rate of permanent singlehood by educational level across cohorts, starting with those born in the 1920s. Disentangling structural effects from gender effects, he questions the existence of a norm of female hypergamy capable of withstanding the changing gender composition of the highly educated, and reveals deep-seated changes in the prevalence of male and female permanent singlehood by educational level.

Correspondence analysis (CA) is a powerful technique, commonly used by sociologists to summarize the structure of the association observed in a contingency table (also known as cross-table). In contrast, approaches derived from CA, or similar in their use, but offering superior properties, are only known by a restricted audience in France: the CA of incomplete contingency table and log-multiplicative association models. This first article uses classic CA and CA of incomplete contingency table to analyze a socioeconomic homogamy table (based on the two-digit catégories socioprofessionnelles of the spouses) from the INSEE Labour Force Surveys conducted between 2003 and 2010. It shows the interest of giving a special status to endogamous couples (in which the spouses belong exactly to the same group), in order to represent better the social space.

Contrary to correspondence analysis (CA), log-multiplicative association models are only known by a restricted audience in France. This second article uses the latter technique to analyze a socioeconomic homogamy table (based on the two-digit catégories socioprofessionnelles of the spouses) from the INSEE Labour Force Surveys conducted between 2003 and 2010. It illustrates the strong resemblance between the two approaches, and highlights the advantages brought by the greater flexibility of association models. They provide a view of the social space both more accurate and easier to interpret than CA, in particular by giving special status to endogamous couples (in which the spouses belong exactly to the same group). They also allow us to analyze specifically men-women asymmetries which emerge from the choice of a spouse (hypergamy), an essential issue poorly apprehended by classical methods.

Despite the relevance of homogamy for the study of social structure, the few existing French studies on the evolution of homogamy have significant weaknesses. This article aims to fill this gap by studying the evolution of educational, social class and social class of origin homogamy (following the Erikson–Goldthorpe–Portocarero—EGP classification) within cohabiting couples, using 42 Labour Force Surveys conducted by INSEE between 1969 and 2011. Homogamy is shown to have clearly declined in all three of the components studied, both in absolute terms and beyond what would be expected as a result of structural changes to the population. Endogamy has declined for almost all groups and the dimensions of social space for partner choice have become largely unimportant. In particular, the specificity of persons with no qualifications, of the self-employed, and of agricultural occupations has very clearly diminished. Only the endogamy of graduates of grandes écoles has increased. Finally, these results are related to changes in class-consciousness, socio-spatial segregation and economic inequality.

In this paper, we introduce R.TeMiS, a free software solution aimed at exploring new dimensions in text mining with a particular focus on media framing analysis. R.TeMiS is especially designed to provide help in a) the automation of corpus construction and management procedures based on the use of large media content data bases, and b) the extension of the range of statistical tools available to social scientists exploring texts through R coding (one and two-way tables, time series, hierarchical clustering, correspondence analysis, geographical mapping…). A case study on the media framing of Julian Assange from January 2010 to December 2011 is conducted. It is based on the analysis of a corpus of 667 news dispatches published in English by the three top international news agencies: Agence France-Presse (AFP), Reuters and Associated Press (AP).

We present the package RcmdrPlugin.temis, a graphical user interface for user-friendly text mining in R. Built as a plug-in to the R Commander provided by the Rcmdr package, it brings together several existing packages and provides new features streamlining the process of importing, managing and analyzing a corpus, in addition to saving results and plots to a report file. Beyond common file formats, automated import of corpora from the Dow Jones Factiva content provider and Twitter is supported. Featured analyses include vocabulary and dissimilarity tables, terms frequencies, terms specific of levels of a variable, term co-occurrences, time series, correspondence analysis and hierarchical clustering.

The persistence of social homogamy is regularly observed; the tendency to form couples in which the woman occupies a lower position than her partner – female hypergamy – is also well documented: love is far from blind to social distinctions. Yet, it was concluded somewhat too fast from this major result that these phenomena have remained stable over time. This thesis shows, based on large-scale survey data, that education, social class and social class of origin homogamy has significantly weakened over the last forty years in France. This trend goes beyond what changes in the population structure would have implied (relative homogamy): the composition of couples has become closer to a random mating situation. Hypergamy has also clearly diminished, and has even reversed regarding education; females hold higher qualifications than their partners since the year 2000. As a consequence, the higher celibacy rate of women with a high social status, in particular that of the higher educated, which stemmed from their unfavorable position on the conjugal market, has converged to that of other groups. The variations of these two dimensions of partner choice over 64 regions of Europe in the 2000s are also sizable. Educational homogamy is higher than socioeconomic homogamy; hypergamy is the most frequent situation, but it is not an absolutely general pattern. The degree of cultural liberalism and of social openness appears as the strongest determinant of these two phenomena. They are negatively correlated with female labor force participation, but their relationship with economic inequalities is ambiguous.
