I assume this has been discussed, but it's pretty interesting.

"BYU has more alumni in these five major Big 12 metros than the Big 12's Iowa State (except in Kansas City) or West Virginia does, and more in Dallas alone than any other potential candidate else has total. Among all schools nationwide, BYU ranks 15th in Dallas and 24th in Houston, with top-25 showings in several other major west-of-the-Mississippi metros."
