According to the 2013 population estimate, Enid, Ok now has over 50,000 residents, and growing consistently. Now that is has over 50,000 residents it should be considered as a metropolitan statistical area, which will make it the fourth MSA in Oklahoma, which is pretty cool. But it probably won't get officially recognized as a MSA until after to 2020 census is conducted if that population holds.

I just think its neat to have a new metro area, as Enid, Ok kinda flies under the radar in Oklahoma, but Enid, is a nice place, from what I hear.
