This report details the results of a study to determine barriers to censusing of Southeast Asian refugees (SEAR) in the United States. In Joint Statistical Agreement with the Bureau of the Census, the research team studied census-related behavior of Southeast Asian refugees by conducting a detailed ethnographic study of Lowland Lao refugees in St. Louis, supplemented by comparative material from research on local Amerasians and by a review of statistical and social science literature. The project also builds upon ten years of participant observation and an alternative enumeration of SEAR in St. Louis after the Dress Rehearsal Census of 1988.
