About the "Republican" White Working Class...

[Antonio the Sixth]

Here are the occupational categories that the Census Bureau recognizes:
           1 MANAGEMENT OCCUPATIONS
           2 BUSINESS AND FINANCIAL OPERATIONS OCCUPATIONS
           3 COMPUTER AND MATHEMATICAL SCIENCE OCCUPATIONS
           4 ARCHITECTURE AND ENGINEERING OCCUPATIONS
           5 LIFE, PHYSICAL, AND SOCIAL SCIENCE OCCUPATIONS
           6 COMMUNITY AND SOCIAL SERVICE OCCUPATIONS
           7 LEGAL OCCUPATIONS
           8 EDUCATION, TRAINING, AND LIBRARY OCCUPATIONS
           9 ARTS, DESIGN, ENTERTAINMENT, SPORTS, AND MEDIA OCCUPATIONS
          10 HEALTHCARE PRACTITIONER AND TECHNICAL OCCUPATIONS
          11 HEALTHCARE SUPPORT OCCUPATIONS
          12 PROTECTIVE SERVICE OCCUPATIONS
          13 FOOD PREPARATION AND SERVING RELATED OCCUPATIONS
          14 BUILDING AND GROUNDS CLEANING AND MAINTENANCE OCCUPATIONS
          15 PERSONAL CARE AND SERVICE OCCUPATIONS
          16 SALES AND RELATED OCCUPATIONS
          17 OFFICE AND ADMINISTRATIVE SUPPORT OCCUPATIONS
          18 FARMING, FISHING, AND FORESTRY OCCUPATIONS

Which ones would be "working class"? 19, 20, 21 and 22? I would assume a good chunk of people in those categories can reach a "middle class" standard of living. What about 13-17, many of whom are actually poorer?

I'd go with 11, 13, 14, 15, 17, 19, 20, 21, 22 - that would give you an overwhelmingly working class sample and capture most of the working class.
