ATUS Industry and Occupation Codes

ATUS industry codes use the U.S. Census Bureau's Industry Classification System, which is based on the North American Industry Classification System. This system is updated periodically. Below is a list of the industry classification systems used by the ATUS and the CPS by year.

2025 through present industry data: 2022 Census Industry Classification System (PDF)
2020 through 2024 industry data: 2017 Census Industry Classification System (PDF)
2014 through 2019 industry data: 2012 Census Industry Classification System (PDF)
2010 through 2013 industry data: 2007 Census Industry Classification System (PDF) (Note: the CPS used the 2007 system starting in 2009)
2003 through 2009 industry data: 2002 Census Industry and Occupation Classification Codes (PDF)

There are only minor differences between the 2002, 2007, 2012, 2017, and 2022 Census Industry Classification Systems.

ATUS occupation codes use the Census Bureau's Occupation Classification System which is based on the Standard Occupational Classification System. This system is also updated periodically. Below is a list of the occupation classification systems used by the ATUS and the CPS by year.

2020 through present occupation data: 2018 Census Occupation Classification Codes (PDF)
2011 through 2019 occupation data: 2010 Census Occupation Classification Codes (PDF)
2003 through 2010 occupation data: 2002 Census Industry and Occupation Classification Codes (PDF)

There are numerous differences between the 2002, 2010, and 2018 Census Occupation Classification Systems and as a result, occupational data are not strictly comparable across all the years.

More information on the differences between the Census Occupation and Industry classification systems is provided by the Current Population Survey. For detailed information on ATUS variables impacted by these changes, see changes between the ATUS Single-Year Data Files document as well as the ATUS Data Dictionaries.
