This article examines intramarriage among three subpopulations of “Other Caucasians” in Hawaii: Armed Forces personnel, born-in-Hawaii residents, and residents not born in Hawaii. The Other Caucasians is a histroically-evolving residual category of ethnic designation known on the United States mainland as "whites". The central hypothesis is that Armed Forces Other Caucasians will have the highest intraethnic marriage rate and born-in-Hawaii Caucasians the lowest. Other hypotheses relate to how the variables of age, education, occupation, island of residence, civil versus religious marriage, and number of this marriage may affect the intraethnic marriage rates.Using 1987 marriage license data from the State of Hawaii Department of Health, the results show support for the different rates of intraethnic marriage by type of Other Caucasian. Additional findings are that civil versus religious marriage, number of this marriage, and island of residence have an effect as well. The conclusion is that the subpopulations of Other Caucasians in Hawii are not similar in their intraethnic marriage practice; and generation of residence is most important for differentiating these categories. In addition, the longer the residence in Hawaii the more likely the Other Caucasians wid share in the tradition of Hawaii, a place characterized by high rates of interethnic marriage.
