RELIABILITY OF ESTIMATES
Estimates in published tables are based on data from the Quarterly Services Survey and
administrative records. To maintain confidentiality, no estimates
are published that would disclose the operations of an individual firm.
The total error of a published estimate may be considered to be comprised of sampling error
and nonsampling error. Individuals who use the
Quarterly Services Survey estimates to create new estimates should cite the Census Bureau as the source of
only the original estimates. See also definitions and technical documentation for
additional information on the Quarterly Services Survey
