This popularly referenced survey gives statistics about the number of atheists in US prisons.
It suggests just 0.21% of the prison population is atheist. There are more scientologists! This is surprising because atheists represent about 15% of the US population.
Now, this survey is often used to show that atheists are more moral. (I lean towards this idea, being an atheist myself.) However, I have been told that such a survey is useless - many "closet" atheists would be worried about reprisal from checking the "atheist" box, especially in a predominantly Christian environment. This would tend to bias the results.
Has any research been performed about this?

Correlation does not mean there's causation, in this case between atheism and not getting convicted. As @DA01 pointed out, atheism is probably correlated with better formal education and higher income, which decrease the chance of ending up in jail. I'm not saying it is so, but it should be verified before jumping to conclusions. I bet that people fond of eating rabbit in a wine and garlic sauce are underrepresented in prisons as well. – Konrad Morawski Aug 29 '12 at 16:30
