I recently came across this study released by the Pew Forum on Religion and Public Life in December. The analysis is based off of a 2007 religious landscape survey. On the link there is an interactive graph of the various states and their responses to the questions.
Utah comes in at 12th in the rank of percent of residents who say that religion is important in their lives; but the state comes in second for weekly attendance at worship services.
Also interesting is that Utah comes in 10th of percentage of people who are certain of their belief in God.
I find that surprising.
I am not sure what their sample size was, or of more details about the survey.
What does interest me, however is that there is clearly some percentage of people who attend church regularly (in Utah) who are not believers or who don’t believe religion is important in their lives. As a caveat, I do know that Utah is not the only mormon/LDS state, and that other states have high populations of mormon believers.
I simply thought that for as sometimes holier than thou that some LDS can be (note I said some, not all)- the data do not seem to show that LDS (particularly those in Utah) are excessively more devout than people in other states or people of other faiths.
