Abstract:
|
A number of different methods for sampling rare populations have been considered, but in random digit dial (RDD) telephone surveys these methods usually are costly or have serious statistical problems. In the California Health Interview Survey (CHIS) conducted in 2001, separate estimates were desired for the following rare populations: five Asian subgroups (Asian Indian, Cambodian, Japanese, Korean, and Vietnamese), American Indian and Alaska Natives, and Latinos in a county. Each of the subgroups poses obstacles to interviewing, including issues such as interviewing language and culturally appropriate interviewing techniques. This paper describes the methods used to oversample these groups, the operational procedures used to deal with interviewing members of these groups, and the statistical estimation schemes that were used to provide estimates for each group. The key idea is to supplement the RDD sample with samples drawn from special lists. We evaluate the efficiency of the method and related procedures and provide some general suggestions for oversampling rare groups in RDD surveys.
