Poor States More Religious

Here is a plot of income vs "religiosity" by State kindly provided by Prof. Andrew Gelman at a Columbia University statistics website. "Religiosity" is measured on a -2 to +2 scale by amount of church attendence. States that voted for Bush are in red and those that voted for Kerry in Blue. Prof. Gelman rightly doesn't draw any conclusions from the data.

It' actually more likely that the correlation is between level of education (rather than religion) and income. Or, maybe not.
