The Quarterly Summary of State and Local Tax Revenues (Quarterly Tax Survey) is comprised of three components: a local government property tax data collection from local property tax collectors (F71), local nonproperty tax data collection from local government tax imposers (F73), and a state government tax data collection (F72). The F71 component has historically resulted from a stratified sample that was fully imputed and estimated using a Horvitz - Thompson weighted estimator.  The estimates from this sample of property tax collectors are subject to sampling error of about 1.5 percent on a national estimate of property tax.  The F72 is a census of all state government tax imposers and is not subject to sampling error.  The F73 component has historically resulted from a nonprobability sample.  As such, sampling errors could not be calculated.
