A few questions for you Sibboleth, or anyone else who cares to answer:
The descriptive terms to describe the categories increasingly feel very arbitrary (but then they were always odd: it makes very little sense to class a foreman and a tradesman in the same social category, particularly if you're looking at voting habits,
I assume the tradesman votes more Tory? I have some vague recollection that people like that were fairly pro-Thatcher.
and the distribution of jobs into categories in some cases feels not so much arbitrary as willfully perverse...
Just curious, but how would a Chartered Accountant be classified? I can't seem to find a decent set of examples for each grade, and could see myself fitting anywhere from C1 to A depending on how you defined the grades... which I suppose is why it isn't very useful.
