Educational homogamy in Ireland and Britain: Trends and patterns

This paper examines the pattern of educational homogamy in Ireland and Britain. Using contemporary data on recent marriages from the early 1970s through to the mid-1990s, we show that these two countries share a broadly similar pattern of educational homogamy, which is quasi-symmetric in character, with no tendency for women to marry up over and above that which can be attributed to the gender difference in educational attainment. In the 1970s, the strength of homogamy was much weaker in Ireland than in Britain. But we discern a clear inter-country difference in how the net strength of homogamy has changed over time. While it has declined in Britain since the 1970s, in Ireland the strength of homogamy has first increased and then levelled off. Our findings are inconsistent with the inverted U-shaped relationship between economic development and homogamy reported by Smits, Ultee and Lammers (1998) - an argument premised on secular change in the criteria of spouse selection. Instead, our results are better understood in terms of Mare's (1991) life course argument that homogamy is inversely related to the time-gap between school departure and first marriage.
