ATUS response rates are calculated based on the sample month. Preprocessing response rates are calculated at the time the sample month is closed out. Postprocessing response rates are calculated when the sample month is closed out and some completed cases are eliminated for data quality reasons. These cases still appear on the public-use data files. These response rates are published annually in LABSTAT.
