Despite the spread of modern familial values and norms and the rapid pace of modernization in Iran, kinship marriages remain a common practice among some ethnic groups, including Turk and Kurd. This study is informed by modernization and development idealism theories to examine factors associated with the practice and attitude of Kurdish and Turkish women to consanguineous marriage, utilizing data from a representative sample of 768 ever-married women residing in the district of Uromiyeh in Iran. The results indicated that consanguineous marriage was more prevalent among Kurds rather than Turks, and Kurdish rather than Turkish women held more positive orientations to consanguineous. Multivariate results showed that being a Kurd than a Turk was strongly associated with the likelihood of practicing kinship marriage and having positive attitudes to consanguineous marriage, while the levels of modernization and development idealism showed no or weak association. The results suggest that ethnic belonging can reinforce consanguineous marriage regardless of being modernized or holding modern development ideals.
