Opposites Attract: Assortative Mating and Immigrant–Native Intermarriage

Opposites Attract: Assortative Mating and Immigrant–Native Intermarriage in Contemporary Sweden. Annika Elwert. European Journal of Population, Dec 2019. https://link.springer.com/journal/10680

Abstract: This paper studies how immigrant–native intermarriages in Sweden are associated with individual characteristics of native men and women and patterns of assortative mating. Patterns of educational- and age-assortative mating that are similar to those found in native–native marriages may reflect openness to immigrant groups, whereas assortative mating patterns that indicate status considerations suggest that country of birth continues to serve as a boundary in the native marriage market. The study uses Swedish register data that cover the entire Swedish population for the period of 1991–2009. The results from binomial and multinomial logistic regressions show that low status of natives in terms of economic and demographic characteristics is associated with intermarriage and that intermarriages are characterized by educational and age heterogamy more than are native–native marriages. The findings indicate that immigrant women as well as immigrant men become more attractive marriage partners if they are considerably younger than their native spouses. This is particularly true for intermarriages with immigrants from certain regions of origin, such as wives from Asia and Africa and husbands from Asia, Africa, and the Middle East. Gender differences in the intermarriage patterns of native men and women are surprisingly small.



Background and Previous Research on Immigrant–Native Intermarriages in Europe and Sweden

Intermarriage between immigrants and natives has increased in most European countries in past decades and is closely related to the proportion of immigrants in the country (Lanzieri 2012). This general increase in intermarriage in Europe is largely related to a substantial increase in intermarriage with spouses from countries outside the EU (de Valk and Medrano 2014). Intermarriage rates in Sweden have risen continuously since the 1970s, and the increase is somewhat steeper for men than for women. Figure 1 displays the proportions of immigrant–native intermarriages (defined here as marriages between a native SwedeFootnote 4 and their foreign-born spouse) and native–native marriages (defined as marriages between two native spouses) of all newly contracted marriages made by native Swedes from 1969 to 2009. As of 1991 the register extracts used in this paper contain an identifier for non-marital cohabitations with common children, which makes it possible to report the shares of native–native cohabitation and immigrant–native cohabitation.

For native women, the shares of immigrant–native marriage and cohabitation are close in size and have changed only marginally since the 1990s; for native men, there is a wider gap with immigrant–native cohabitation displaying lower rates with little increase over time and immigrant–native marriages displaying higher rates with a more pronounced increase over time.
In earlier decades, intermarriage between native Swedes and immigrants was dominated by intermarriage with other Nordic citizens, particularly Finns (Cretser 1999). In more recent years, the increase in intermarriages can be largely accounted for by the increased number of marriages with partners from outside Europe, and Thailand has replaced Finland as the most frequent country of origin for intermarried immigrant women (although Finland remains the most common country of origin for intermarried immigrant men; Haandrikman 2014).
Most of the previous research on intermarriage has a strong emphasis on immigrant integration (Kulu and González-Ferrer 2014). Intermarriage in this regard is thought to indicate social integration (Kalmijn 1998). Studies in this line of research largely focus on the intermarriage rates of different immigrant groups, since these are understood to be a measure of group closure and social distance. Individual characteristics that are associated with immigrant–native intermarriage are typically contrasted with those that are associated with endogamous immigrant marriage (for example, González-Ferrer 2006; Kalmijn and van Tubergen 2006; Dribe and Lundh 2008 on Sweden). Studies that take into account the native side of intermarriage are comparatively rare. They often show that native men who intermarry are more often lower educated and have a lower income (Guetto and Azzolini 2015; Haandrikman 2014), are older (Glowsky 2007; Guetto and Azzolini 2015; Niedomysl et al. 2010), and may encounter difficulties in finding an attractive partner in the native endogamous marriage market—difficulties that could be related to their age (Glowsky 2007) or to local shortages of native women (Östh et al. 2011).
As Kulu and González-Ferrer (2014) note, patterns of intermarriages are gendered. In many countries, more foreign-born women than foreign-born men are intermarried (and the reverse applies to natives). Such patterns can be explained by selective immigration and the structural constraints of the marriage market or by selective marriage patterns of the native majority population. In contrast to other European countries, these patterns in Sweden’s case can be partly explained by gendered patterns of marriage migration; i.e. native men (and to a lesser extent native women) marrying women (men) from economically poorer countries. Marriage migration to the native majority is a growing phenomenon particularly in Sweden, although it does exist elsewhere as well (de Valk and Medrano 2014). Niedomysl et al. (2010) show that assortative mating patterns in marriages of marriage migrants and natives deviate from the Swedish norm. While both the opportunity structures and individual characteristics may be related to the likelihood of marrying a marriage migrant, individual characteristics such as age and income appear to be of greater importance (Östh et al. 2011).

Conclusion

Since marriage is one of the most intimate relationships in life, marriage between different social groups has the potential to reveal the social distance between them. Theoretically speaking, if marriage means accepting one another as equals, intermarriage can be an indication of openness towards other social groups (Kalmijn 1991). Since marriage is also always related to status (Kalmijn 1998), adopting the openness perspective would mean that immigrant–native marriages are not expected to differ from native–native marriages with regard to status homogamy, or, if they do, this is in a random fashion. If intermarriage is related to low individual attractiveness in the marriage market or if there are systematic differences in assortative mating patterns, this can be seen as an indication that status considerations are important determinants of intermarriage. Accordingly, members of different social groups do not regard each other as equals.
This study focuses on marriages between immigrants and natives in Sweden and in particular on assortative mating patterns by education and age. Marriage market status both in terms of economic and demographic characteristics of native Swedes is associated with intermarriage. The findings show that—broadly speaking—native Swedish men and women with lower status in economic and demographic characteristics are more prone to intermarry, which is similar to the findings of Östh (2011) and Haandrikman (2014). While these patterns support the idea that individuals of lower status in the marriage market suffer from a competitive disadvantage and are hence more likely to marry immigrants (Fu 2001; Gullickson and Torche 2014), the patterns found among native men also support the idea that the highly educated are more likely to be open towards immigrants (Hello et al. 2002; Wagner and Zick 1995).
Moreover, the findings of this study show that there are systematic differences in assortative mating patterns between native endogamous marriages and intermarriages, which would support a status exchange interpretation. With respect to educational-assortative mating, intermarriages display higher levels of educational heterogamy across immigrant groups with different levels of status in society, but the patterns appear to be more random than systematic. With respect to age, however, age-assortative mating patterns display systematic differences that indicate the existence of age status exchange in Swedish intermarriages. Intermarriages are generally more heterogamous with regard to age as well. The patterns of age hypogamy with a substantial gap for native Swedish men and women along the lines of a hierarchy of immigrants nonetheless indicate that for some immigrant groups intermarriage with natives is more achievable when they have other attractive characteristics to offer in return. These associations are particularly pronounced for intermarriages with marriage migrants, where these patterns closely follow the theoretically predicted hierarchy of immigrants. Marriage migrants can be regarded as a different category to resident immigrants because the union with a Swede gives them the opportunity to be given secured residence, which is likely to make them more receptive to status exchange.
Sweden often appears to be a comparatively open society with low levels of educational homogamy and high levels of gender equality. Similarly, intermarriage between immigrants and natives has been thought of as indicating the openness of natives towards immigrants and accepting them as “equal lifetime partner[s]” (Kalmijn 1991). The findings of this study challenge this view and support the notion that country of birth serves as a boundary in the native marriage market. This study illustrates the fact that this boundary manifests itself not only by excluding immigrants of certain immigrant groups from the pool of marriage partners but also by allowing them in if they have something to offer in return. In the Swedish case, this is likely to be age.
