I've updated this quiz to have a population cutoff of 1 million. This means that Anchorage is no longer eligible since it has a metro population of only 400,000.
Yeah, I'm surprised it's so far north... (It's really not, but apparently people don't like to build too many cities in the northern part of the country)
Is it bad that I missed the one nearest my hometown because I thought it was too small to make the list? (Same with the others I missed, unfortunately.)
It includes a lot of filler area and cities that are a long way off and not remotely part of the urban area, like Holland and Muskegon. The U.S. does "metropolitan" areas by counties, which have no rhyme nor reason to their borders and may be enormous or tiny. Some twin cities wind up being in different "metropolitan" areas of larger cities an hour away because of arbitrary and functionally useless county lines. It's a lazy method for government workers' convenience but winds up being a waste of time if it's just a bunch of false numbers.
NYC's metro area includes parts of Connecticut, New Jersey, and Pennsylvania. The city proper population is a little over 8 million. The metro area is closer to 19 million.
St. Paul should work for the Minneapolis-St. Paul Metro Area. Both are the main cities in their metro area. Similarly, Fort Worth and Arlington both should work for Dallas when talking about the Metroplex. Fort Worth has nearly a million people while Arlington has about 400,000.
