45. Utah
When we think of Utah, the first word that comes to mind is “Mormons,” and people living in Utah are probably sick of people from other states thinking they’re all Mormons. This is another one of those stereotypes, however, that is completely based on reality; over two million Mormons live in Utah, which is one third of the total number of Mormons in the U.S.
So perhaps not everyone in Utah are Mormons, but in a state where it’s not uncommon for kindergarten children to be aunts and uncles, it’s not far-fetched thinking that every other person that comes from there is a Mormon. Another explanation, however, is that the birthrate in Utah is among the highest in the country, and even non-Mormon families have a lot of children, so this creates somewhat of a confusion.
