Code Lists and Crosswalks
Industry and occupation code lists for each year of the American Community Survey (ACS) are available here.
Because the industry and occupation classifications have changed overtime, crosswalks have been developed to facilitate analysis of data across classification systems. The most recent code lists and crosswalks are available for download.
