1990 Census and Census 2000 Industry and Occupation Classification Systems
This paper describes the changes in the industry and occupation classification systems used in the 1990 Census of Population and Housing (1990 Census) and the classification systems used in Census 2000. As a result of these changes, many 2000 industry detailed categories and major groups and most 2000 occupation detailed categories and major groups are not comparable to similar categories and groupings in the 1990 and earlier censuses. Included are detailed tables called "crosswalks" which show the proportional flows for individual industry and occupation categories between the two census years. The crosswalks in this report enable analysts to convert the 1990 data at any level of detail into the newer Census 2000 classifications.
