Connubium

Connubium Definition

Connubium refers to the prescribed relationship or system of marital exchanges between distinct social groups. It describes a situation where one group of males possesses either the power or the obligation to marry within a specific group of females. This concept is often used in anthropology to examine the structural arrangements governing intergroup marriage, which can be interpreted in relation to concepts such as the incest taboo, the formation of political alliances, and the delineation of symbolic group boundaries.

Connubium and Homogamy

The question “Who marries whom?” relates to patterns of partner choice, which is often studied through the lens of homogamy—the tendency to marry individuals from the same social group or those sharing similar characteristics. Sociologists use this framework to investigate how marriage patterns reflect the structure of society. Research traditionally focuses on three key characteristics that influence partner selection: race/ethnicity, religion, and socioeconomic resources. The degree of homogeneity observed across these dimensions allows researchers to evaluate the openness of boundaries between different ethnic, religious, or socioeconomic groups.

Socioeconomic Homogamy

Socioeconomic homogamy relates directly to the structure of social stratification and inequality. In a society exhibiting maximum socioeconomic homogamy, individuals with high educational and occupational status tend to marry partners of similar status. Conversely, in societies with minimum homogeneity, there is greater mixing between high and low socio-economic classes. The distribution of inequality among couples is highest in societies with maximum homogeneity and lowest in those with minimum homogeneity.

Theoretical Explanations

The patterns of partner choice are explained by several competing theories. Modernisation theory suggests that the shift from agrarian to industrial society diminished parental control over marriage, increasing opportunities for individuals from different groups to interact. This perspective posits that as family functions shifted towards emotional units and welfare states developed, the need for parents to strictly control offspring’s marriages decreased, leading to a predicted decline in socioeconomic homogamy over time.

The educational system theory argues that increased participation in education segments the marriage market, favouring educational homogamy. This is because prolonged schooling fosters homogeneous environments and postpones marriage until educational milestones are met, thereby limiting exposure to partners with differing socio-economic resources.

Methodological Considerations

Comparative analysis of intergroup patterns involves methodological complications stemming from the marginal distributions of characteristics within populations. For instance, the level of homogamy is negatively correlated with the heterogeneity of a population regarding a specific characteristic. Empirical research has historically focused only on married couples, excluding singles, which is now considered inadequate given changes in living arrangements. Consequently, the unit of analysis has shifted from the couple to the individual, focusing on how individual preferences, third-party control, and partner availability affect an individual’s outcome in the marriage market.
