I read 86% of those who committed suicide had middle names rhyming with ‘Hussein’, while the other 17% who quoted statistics were found to be liars. =;^)
Or perhaps it is almost every house has a gun. (which is a good thing) The problem is gun are extremely successful in suicides. Drugs, slitting wrists etc are not successful.
A better statistic would be a suicide attempts normalized for population.
Your post leads one to suspect that the suicides in Utah (remember UT is only 9th) are all non-Mormon. I would suspect that is NOT the case. I would suspect that factoring in religion there is NO difference.
