Based around Utah and the Mountain West, these 41 counties are the centers of the nation’s Mormon population. The Enclaves are one of the youngest types in the ACP, with 31% of the population under the age of 18. They are also one of the least diverse types, with a population that is 90% white and 1% African American – 11% of the population identifies as Hispanic (Hispanics can be of any race). The LDS Enclaves are reliably Republican, but they were especially strong for Republican Presidential Nominee Mitt Romney, the first major party Mormon presidential candidate, in 2012. Romney won 74% of the Enclaves’ vote.
