Audit of the HAO analysis files, site I, year 3
Assesses the completeness and reliability of administrative data collected by the housing allowance office (HAO) in Brown County, Wisconsin (Site I of the Housing Assistance Supply Experiment) during the first three years of the housing allowance program--June 1974 to June 1977. Checks of the data records showed errors in less than 0.5 percent of 2.4 million response fields; virtually all were corrected. Few errors were found in matching records to create three analysis files. Manual examination of the response frequencies (marginals) of all 800 variables--including 26 derived variables--showed errors in only 13, no variable containing more than five erroneous values. The audit revealed both the need for better recordkeeping at the HAO and some weaknesses in audit strategy, such as the failure to check for chronological inconsistencies in each client's record.
