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.
