In recent years, RTI has used a composite size measure procedure for achieving selfweighting samples for multiple domains in multistagedesigns. The procedure requires some knowledge of population counts, either estimated or actual count of the numbers of elements in the population, for each domain in each sampling unit. This procedure can also be used in a two phase design in which the domain membershipinformation is collected in the first phase sampling units and used in the second phase. The procedure is well suited to sampling fromlarge list frames with clusters of elementary units that can serve as primary sampling units to reduce data collection costs. RTI has usedthis procedure to sample customers for personal interview from the billing file of amajor Southeast utility, to sample Medicaid recipientsin state-level surveys (Lynch et al. 1986), for a Medicaid household survey (Folsom and Iannacchione, 1980), and to sample patientrecords at a sample of hospitals in Florida (Williams et al., 1978).
