Turk and Kurd stand at the second and third ranks respectively, followed by other ethnic groups including Lor, Baluchi, Arab and Turkmen. Ethnic groups constitute appropriate context for studying demographic characteristics and dynamics of a population (McDonald, 2002). In the NorthWest provinces of Iran, Kurds and Turks have been living together in the same neighbourhood for many centuries. Nevertheless, the prevalence of consanguineous marriage among Kurds (47.3 percent) is 1.3 times grater than Turks (35.6 percent) in the country (Abbasi-shavazi and Khani, 2009: 52). It is not clear whether the differential in the rates of consanguineous marriage among Kurds and Turks in Iran is due to their ethnicity per se or to differing levels of modernization and development. These questions have not been well examined by previous studies. This study aims to bridge this gap in the literature, utilizing data from a recent local survey conducted in the district of Uromiyeh, where Kurds and Turks live together. THE RESEARCH SETTING The study population of this research include Turkish and Kurdish women living in the Figure 1. Geographic Distribution of Ethnic Groups in Iran. Source: Adapted from Torabi and Baschieri (2010: 37). 390 Journal of Comparative Family Studies district of Uromiyeh, the capital of province of West Azerbaijan, which is located in the north west of Iran, bordering Turkey. The province and Uromiyeh have a heterogeneous population in terms of ethnicity and religion. The population of Uromiyeh is largely made of two major ethno-religious groups of Shiite Turks and Sunni Kurds. In such a context, Kurdish people have been treated as a minority group of populations that are socially, economically and politically discriminated. The literature indicates important differences in cultural characteristics of marriage and childbearing among Turkish and Kurdish people, living in Uromiyeh (Hosseini and Mehryar 2006; Abbasi-Shavazi and Hosseini, 2009; Hosseini and Abbasi-Shavazi, 2009; Hosseini, 2012). Overall, these studies show that compared with Turks living in West Azerbaijan, Kurds are more in favour of extended family, fatalism in reproductive behaviour, ethnic homogamy, son preference, economic advantages of children, early marriage, large ideal number of children, and preference of marriage over employment for girls.
