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 Quarterly Services Survey estimates
to create new estimates should cite the Census Bureau as the source
of only the original estimates. See technical
documentation for additional information on the Quarterly Services
