This review article maps a specific area of divorce research, which is important, but almost uncited in Czech sociology of the family: the connection between divorce and gender. It shows that although the concept of gender is implicitly embedded in the social phenomenon of divorce, the majority of empirical research on divorce conceptualises gender only as differences in the behaviour of men and women. This approach can be useful for explaining the gender structure of the causes and consequences of divorce. Here more attention is given to studies that explicitly mention the concept of gender at the structural, institutional, and interactional levels. It reviews the literature on gender as part of the institutional environment, and in this context it introduces the perspectives on changing gender roles as a factor influencing divorce and the literature mapping the potential of divorce to change the gender order of society. These theoretical perspectives are relatively rare in the divorce literature; therefore, it is useful to provide Czech readers with a review of some inspiring conceptualisations and put them in the context of knowledge about divorce in the Czech Republic.
The article examines the long-term changes and the age homogamy of marriages that took place in the Czech Republic between 1920 and 2000. The analysis of data acquired from a study of vital registration is divided into a descriptive part - describing the age structure of the marriage market and the absolute degree of age homogamy - and an exploratory part - creating a log-linear model of the structure and changes of relative age homogamy. Three hypotheses are formulated in connection with the latter part of the analysis, of which the hypothesis about increasing age homogamy seems acceptable. Results from the descriptive analysis and the models show that age homogamy has been increasing during the 20th century, both in the case of first marriages and remarriages. The hypothesis about the greater degree of age heterogamy in the case of remarriages can also be accepted, while the testing of the third hypothesis, that the older the marital partners are the more heterogamous their age structure, proved inconclusive and requires further investigation.
