This is half right. Tampa Bay is the name of the metro area, though Tampa is the principal city of that metro area. Just as Twin Cities is the name of the metro area for Minneapolis-Saint Paul, Minneapolis is the principal city of that metro area.
To be technical, the Census Bureau does have official names for metropolitan areas, based on their largest cities. So officially it's the Tampa–St. Petersburg–Clearwater MSA and the Minneapolis–St. Paul–Bloomington MSA.
I really expected there to be a lot more towns in Utah on this list - between Ogden, Orem, Moab, and Sandy, I would have thought at least one had 100k people in it.
Now Orem and Sandy are right on the cusp, with Ogden and Lehi just behind. Moab is about 100k away from making the list. If the list was expanded a bit more we could probably see 5 Utah cities on it.
