NAICS 1997 has been revised to the NAICS 2002 version. NAICS 2002 is the same as NAICS 1997 for 16 of the 20 sectors. Construction and wholesale trade are substantially changed, but the revisions also modify a number of retail classifications and the organization of the information sector. The Current Employment Statistics (CES) survey will convert directly from SIC-based estimates to NAICS 2002; no estimates will be published using NAICS 1997. The CES program will begin publishing State and Area data on a NAICS 2002 basis with the release of January data in March 2003.
