Current Employment Statistics - CES (National)

Ratios of Employment From SIC to NAICS and From NAICS to SIC

The following tables show for the private sector, ratios of employment from 2-,3-, and 4-digit SIC series to NAICS, and from NAICS to 2-, 3-, and 4-digit SIC series. The tables were prepared using first quarter 2001 data from the Quarterly Census of Employment and Wages Program and can be used to evaluate time series breaks and correspondence between SIC and NAICS in the CES series. Ratios may not add up to 100 percent for an SIC or NAICS series because ratios less than one percent were excluded, and not all NAICS industries will be published under CES—part of an SIC series may go to an unpublished NAICS industry or a combined NAICS series. See CES Series to be Published Under NAICS.
