L’analyse statistique des tables de contingence carrées - L’homogamie socioprofessionnelle en France II. L’apport des modèles d’association

Abstract

Statistical Analysis of Square Contingency Tables - Social-professional Homogamy in France II. The Contribution of Association Models: 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.
