ATUS industry codes use the U.S. Census Bureau's Industry Classification System, which is based on the North American Industry Classification System. The 2007 Census Industry Classification System was incorporated beginning in the 2009 CPS and 2010 ATUS; it replaced the 2002 Census Industry Classification System, which was used by ATUS and CPS from 2003 until the 2007 classification scheme was implemented. There were only minor differences between the 2002 and 2007 Census Industry Classification Systems.
ATUS occupation codes use the U.S. Census Bureau's Occupation Classification System, which is based on the Standard Occupational Classification. From 2003-10, ATUS and CPS used the U.S. Census Bureau's 2002 Occupation Classification System; starting in 2011, ATUS and CPS began using the U.S. Census Bureau's 2010 Occupation Classification System. There are numerous differences between the 2002 and 2010 Census Occupation Classification Systems and as a result, occupational data beginning in 2011 are not strictly comparable with earlier 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 2003 to 2011 ATUS as well as the 2011 ATUS Data Dictionaries.
