Data Quality Data quality/nonsampling errors: |
|
|
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 2004 Annual Survey of Public Employee-Retirement Systems was 97.30%. The response rate was calculated as the number of responses received divided by the number of parent governments mailed minus the number of governments that were determined to be out of scope. Units reporting Total Holdings and Investments (Z81) are counted as respondents. The weighted response rate to the 2004 Annual Survey of Public Employee-Retirement Systems was 99.92%. The weighted response rate was calculated as the value of Total Holdings and Investments (Z81) received divided by the estimated total value of Total Holdings and Investments of those units mailed minus those governments that were determined to be out of scope. |
