Note:

The Census 2000 occupational classification has 509 categories. Of these 369 exactly match SOC detailed categories; another 127 match the SOC at its broad category or minor group level. There are 13 aggregates of multiple SOC categories that do not have an exact match to a single SOC code.   Since each of the 13 aggregates contains more than one SOC equivalent, the Census Bureau will us an "X" or "XX" designation in tabulations that show data for these aggregates.  These aggregates are as follows:
