Data Quality

Nonsampling Error: Despite efforts made in all phases of collection, processing, and tabulation to minimize errors, the survey is subject to non-sampling errors such as the inability to obtain data for every variable for all units, inaccuracies in classification, mistakes in keying and coding, and coverage errors.

Overall Unit Response Rate: The overall unit response rate is calculated as follows:

Overall Unit Response Rate= Number of units who reported all key variables for at least one function X 100
Number of units in the eligible universe

Total Quantity Reponse Rate: The total quantity response rate is calculated as follows:

TQRR for tax category= Sum of response data for tax category + Sum of equivalent quality-to-reported tax category X 100
Sum of all data for tax category

Tax codes with their corresponding description and TQRR are available in the Annual State Tax Collection Survey Methodology.
