Recent efforts on the part of survey researchers to understand the characteristics and needs of homeless individuals have been hampered by factors which make it extra ordinarily difficult to draw representative samples of this population. To date, only one study (Rossi et al., 1987) has drawn a probability sample of homeless persons that includes unsheltered individuals. Because the design of the Rossi study can only accommodate a short interview and is best carried out in one night, additional designs that allow more lengthy interview protocols and data collection periods are needed. An effort to draw a probability sample of homeless adults in the inner-city area of Los Angeles resulted in a sampling design that meets these criteria. This article describes this design in detail.
