"Is religion an important part of your life?" is a very general question. I'd criticise it due to its ambiguity; you can be a militant Atheist and still say religion has is an important part of your life, based on how it affects you (although I'm sure it's not the case here - I'm just being a nit-picker).
Secondly, although I'm not completely familiar with US geography, it seems to me as though many of the states at the top of the list are southern states. Again, I'm not American, but I'd be willing to wager that there are some drastic cultural differences between the "northern" and the "southern" states, leading me to believe that you can't simply pin all of the problems on "religion".
And finally, this survey is limited to the United States, and therefore cannot give an accurate measure when discussing something so universal such as religious beliefs. Perhaps it has some value for studies strictly pertaining to the United States, but to make a generalisation about religion based on a single country is one of the most ignorant mistakes you can make when talking about universal trends, no?
For instance, I can take Switzerland - a very religious country that has, on the whole, rejected the idea of separation between church and state - has a high income, low poverty rates (I think...), low murder rates etc.
Can I then draw the conclusion that religious people on the whole are smart, peaceful and wealthy?
So basically I'd say that the information presented in that table isn't worth a whole lot, as there are many factors that contribute to income, theft, divorce rates etc., not just religion. I would also say that utilising that information, you cannot make a statement about religion around the world, since it only comes from a single nation.
