Audit of the survey of residential buildings, site I, wave 3

Assesses the completeness of 1976 survey data on the observable characteristics of properties and buildings in Brown County, Wisconsin, Site I of the Housing Assistance Supply Experiment (HASE). To avoid gathering data expected to be largely redundant, the wave 3 survey was addressed to a much smaller sample than at previous waves. The sample list contained 139 buildings: 11 newly built on properties in the longitudinal HASE sample, 69 in sample of newly developed residential properties, and 59 in a sample of properties containing federally subsidized housing. Observations were completed for 107 buildings, 77 percent of the sample. Auditors subjected the survey data (already "cleaned" of clearly incorrect and implausible responses) to various checks for subtle errors. Each error report was investigated and the relevant response was confirmed without change, corrected, or replaced with a code explaining the absence of usable data.
