Marriage Patterns of Indigenous Peoples in Taiwan: Cohort Effect, Generational Heritage and Ethnic Difference
Compared to the spatial segregation period before the 1950s, indigenous people have had migrated from tribal to metropolitan areas since 1970 and had more daily contact with Han Chinese and other ethnic group people; hence, the marriage pattern of indigenous people has changed. Based on Taiwan Indigenous People Survey data and the Language Endangerment in Formosan Languages Survey data, this paper portrays the dynamic marriage patterns of indigenous people. The main findings are as follows: (1) The younger birth cohort has a higher racial intermarriage rate and lower intra-marriage rate. (2) The generational inherited marriage pattern within family varies by intermarriage type: offspring's preference for racial intermarriage is similar to their parents, but the ethnic intermarriage does not show a signifi-cant heritage pattern. (3) The marriage pattern of some ethnic groups involves more intermarriage with Han Chinese than with other ethnic groups such as Thao, Kavalan, and Saisiyat. (4) The intimacy among ethnic groups is different: Hla'alua, Kanakanavu, and Bunun are much closer to each other, as are Kavalan with Amis. This paper portrays marriage patterns among Taiwan indigenous people based on the merged data from the two surveys, which provide rare and valuable information on inter-ethnic marriage of different indigenous tribes. The paper presents the increasing plurality of patterns of inter-ethnic marriage, manifests the different tendency of each ethnic group, and reveals the factors facilitating inter-ethnic marriage.
