Sampling nonresidential properties : site I
Two surveys, one of owners of unimproved land and the other of owners of nonresidential properties, were conducted in Brown County, Wisconsin, as part of the baseline series of surveys for the Housing Assistance Supply Experiment. The surveys were major instruments in HASE's monitoring of postbaseline additions to housing stock. From the county's total number of urban nonresidential tax parcels a first stage sample of 9,711 was selected and divided into improved and unimproved properties. Stratification and resampling yielded a total of 806 unimproved properties and 178 improved convertible properties. The design target for completed baseline records was 200 properties for each survey, and was easily met for unimproved properties. For the second survey, HASE researchers decided to rely on careful fieldwork to raise the completion rate to 56 percent rather than obtaining a supplemental sample.
