Description

INDNAICS reports the type of establishment in which the person worked, in terms of the good or service produced. INDNAICS codes industries according to the North American Industrial Classification System, which was developed in 1997. This categorization system is substantially different from industry classifications used in prior years.

For workers employed during the previous week, the data refer to the job at which the person worked the greatest number of hours. For unemployed persons or those out of the labor force, the data refer to their most recent job, if it was within the previous five years.

A crosswalk of INDNAICS codes for the 2000 Census and the ACS/PRCS from 2000-onward is available here:

The variable IND provides a numeric industry classification that is closely related to the INDNAICS scheme. A crosswalk between IND and INDNAICS codes is available here:

IND to INDNAICS Crosswalk

User Caution: INDNAICS contains alphabetic characters (See IND for a fully numeric classification of industry).

Note: The IND to INDNAICS crosswalk is reflective of the codes in the ACS PUMS data files, which slightly differ from the codes found here: Full list of Census provided Industry and Occupation Codes.

INDNAICS is an 8-digit alphanumeric string variable which reports the type of establishment in which the person worked, in terms of the good or service produced. INDNAICS codes industries according to the North American Industrial Classification System, which was developed in 1997. This categorization system is substantially different from industry classifications used in prior years.

Comparability

This variable is available for the 2000 Census and the ACS/PRCS from 2000-onward. The variable IND provides an alternative numeric industrial classification that is similarly detailed.

NAICS codes are updated at five-year intervals; the following groups of samples use different coding systems and thus have comparability issues:
2000-2002 Census and ACS samples used the 1997 NAICS
2003-2007 ACS/PRCS samples used the 2002 NAICS
2008-2012 ACS/PRCS samples used the 2007 NAICS
2013-2017 ACS/PRCS samples used the 2012 NAICS
2018-2022 ACS/PRCS samples used the 2017 NAICS
2023-2027 ACS/PRCS samples used the 2022 NAICS
Links to the crosswalks between INDNAICS codes over time and IND to INDNAICS codes over time are available on the Description tab.
