Mhays you're right the Springs has suburbs, but nothing like other stand alone metro areas of peer cities it's size (Tucson, Raleigh, Virginia Beach). It's too dependent upon Denver and just close enough geographically to have developed into it's own significant metro area. In the peer example of Tucson, you see the geographical separation with Phoenix being just far enough that Tucson has a significant suburb network of it's own. Colorado Springs however is the 42nd largest city in the US but only the 79th largest metro area by population. These are the only suburbs in the Springs MSA above 10k people in 2012.
