In the “Conservatives are nicer than liberals” controversy, there was a question about who has more money, conservatives or liberals. I’ve written a lot about income and voting, but I realized I’d never actually looked at income and political ideology. Here are the data, from respondents to the Pew pre-election polls in 2008:
The poorest people are more likely to be liberal, and the richest are more likely to identify as moderate rather than conservative, but overall there’s less going on here than I would’ve expected.
In contrast, the relation between income and party identification is strong, and goes in the expected direction:
There must be a lot of low-income moderate Democrats and high-income moderate Republicans out there.
P.S. For the purpose of understanding charitable giving, I’d rather know wealth than income. Or maybe something like “disposable income.” It’s harder to get this from survey data, though.
