Announcements
Effective with the March 2013 release for the fourth
quarter of 2012, quarterly services estimates will be based on
a new sample and published on a 2007 North American Industry Classification
System (NAICS) basis. In addition, quarterly services estimates
will be revised to reflect new seasonal factors and results of
the 2011 Service Annual Survey. For further information on the
new sample or the impact of adopting the 2007 NAICS definitions,
see our FAQs.

economic indicators, download the America’s Economy app for Apple

With the release of the 2010 Service Annual Survey (SAS) estimates in February 2012 , revised revenue estimates for employer plus nonemployer
firms will be provided in Table 1.1 for 2009 and all previous years. Estimates will be revised for the entire time series to reflect
improvements in the coverage of nonemployer businesses (i.e., businesses with no paid employees) that were implemented with
the release of the 2009 Nonemployer Statistics.
For additional information on these improvements and their effect on the nonemployer totals, see the
Nonemployer Statistics home page.
Revisions to all other published estimates may occur because of corrections made
to previously reported data and the replacement of imputed data with reported data obtained from the company.
