In other surprises: fans of opera and classical music are most likely to have PhDs, have high incomes and not accumulate excessive credit card debt, and (along with jazz fans, who are a shade beneath them) are most likely to drink wine.
Too lazy to look. Did they correct for the effect of age?
I remember a similar study done ages ago in Italy yielding similar results, except that Verdi and Puccini were the "lowbrow" choices. Apparently, only the lower middle class listen to the more "accessible" homegrown composers.
That's a fairly limited range of musical genres - no mention of the various types of metal, punk, indy, etc. etc. To think there would be no one with a PhD who liked chart pop would be indicative of a very limited sample. How did they decide what group someone belonged to? I know my musical collection would not fit neatly into any of those genres and I suspect many of the people that read this blog would be in a similar position.
