Data Quality Data quality/nonsampling errors (including response rates): |

|
Although every effort (as described in the Data Processing section) is made in all phases of collection,
processing, and tabulation to minimize errors, the sample data are subject to nonsampling errors such as
inability to obtain data for every variable from all units in the sample, inaccuracies in classification,
response errors, misinterpretation of questions, mistakes in keying and coding, and coverage errors.
These same errors may be evident in census collections and may affect the Census of Governments data
used to adjust the sample during the estimation phase and used in the imputation process.
The overall response rate to the 2006 Annual Survey of Government Finances was 79.72%. Data for the 50 state governments were complied from state records supplied by each state government. The response rate was calculated as the number of responses received divided by the number of parent governments mailed. |
