  Notes: See Glossary for definitions. Relative Standard Error is designed to indicate error due to sampling.  However, nonsampling error is important for all surveys, census or sample.  See Technical Notes for further information. Values for 2008 are preliminary. It should be noted that such things as large changes in retail sales, reclassification of retail sales, or changes in billing procedures can contribute to unusually high relative standard error.
