The NAICS coding structure has been revised. While the recommended indcode has not been changed in the WID, revisions will need to be made to lookup tables to avoid foreign key violations as new data comes out. Updates to indcodes (full or just the additions) and naiccode are available.
QCEW data is being reported using new codes and how that is implemented and affects imports to EXPO will vary from state to state.
CES data code changes took affect with 2018 data and requires new codes to be added. For state level data there may be additional changes – series are sometimes added and dropped for other reasons and those changes take affect with January data.
For details of the CES changes, look at the BLS documentation.
