|The IWIN Quarterly Census of
Employment & Wages tool provides data on industry
employment, wages, and number of business establishments.
Beginning in 2001, data
are reported using the North American Industry Classification
System (NAICS). Data Prior to 2001 are organized by the Standard Industrial
Classification (SIC) and some statistics are available upon request. Because of
significant differences between these methods of industrial classfication, data
reported using the NAICS coding methodology are not comparable with the prior years (SIC).
2001-CURRENT are also available at the Quarterly Census of
Employment and Wages page.
