NAICS to SIC Employment Ratios for 4-Digit SIC Series

The following table shows, for the private sector, ratios of employment from 4-, 5-, and 6-digit NAICS series to corresponding 4-digit SIC series. The table was 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 NAICS and SIC in the CES series. For example, for CES NAICS series 10-212319 Other stone mining and quarrying, approximately 66.2 percent of the employment will come from SIC series 10-1429 Crushed and broken stone, and 33.8 percent will come from SIC series 10-1499 Dimension stone and other nonmetallic minerals. Ratios may not add up to 100 percent for a 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one percent were excluded, and not all NAICS industries will be published under CES—part of an SIC series may go to an unpublished NAICS industry or a combined NAICS series.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.
