Assesses the completeness and reliability of administrative data collected by the housing allowance office (HAO) in St. Joseph County, Indiana (Site II of the Housing Assistance Supply Experiment), during the first three years of the housing allowance program--December 1974 to December 1977. Checks of the data records showed errors in less than 0.5 percent of 4.3 million response fields; virtually all were corrected. Few errors were found in matching records to create three analysis files. Examination of the response frequences (marginals) of all 800 variables--including 26 derived variables--showed errors in only 22; apart from two variables, none contained 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.
