The claim: Edwards, 301,000
What it really is: Edwards Air Force Base is the home of the Air Force's Flight Test Center and has been the test site for multiple famous military aircraft.
Because this base is a testing facility, and such a large one at that, the base would require multiple large buildings for supporting the aircraft located and tested here. Most of these buildings are located around the runways as well, and not away from them.
The base also has on base housing for families of personnel that are stationed there.
