Re: Another city gets light rail
You can think of an MSA as an area where people shop, work, and live. If people living 20 miles away from a city centre venture to the city limits often enough (not sure what the figure is) to shop or work OR if they must come to the central city for urban services, then it is usually considered MSA. CSA is the surrounding area from the MSA where people venture into the central city less often but still do for essential goods and services.
The size of OKCs MSA and CSA does not surprise me at all. You all think of Cincinnatti and Seattle as big cities - but in fact, it is their CSAs that make them big. Cincin has less than 300k people in the central city but their MSA includes southern OH and Northern KY. Their CSA touches Louisville MSA! Some would even argue that Louisville should be included into Cincin CSA because healthy pop ventures to cincin for goods and services.
Ditto that for Seattle, which is 560k central city and 1.7 mil MSA (which are cities that more or less tough Seattle (just like OKCs MSA). Well, Tacoma also has a MSA (which is 1.2 mil) - BUT for high-end essential services nearly everyone in the Puget Sound travels to Seattle (or Vancouver BC). So, Seattle's CSA is nearly 4 million people! and includes an area the size of OKC to Tulsa (NO KIDDING!!!). Do people in Tacoma really care about Seattle, NO but for hi end shopping or major league sports, well you have to go to Seattle or Vancouver, but Seattle is much closer. So, the Tacoma MSA is part of the Seattle-Tacoma-Bremerton CSA.
I sincerely doubt that Tulsa MSA would ever join into the OKC CMSA. Tulsa has enough essential services to keep their MSA coming there. Aside from Transient visitor or state commerce (or the recent concerts, entertainment, and sports) most Tulsans do not have to come to OKC, and vice versa.
But, I bet you that Stillwater goes to OKC quite often! As does Enid, Lawton, and most every other city in the original 405 area code. That is why OKC got a CMSA! Because an expanded population relied heavily on OKC than just the MSA.
Now, why was Pot county dropped from OKC MSA and moved to the CMSA? I have no idea. Technically, the OKC limits tough Pot County, which is indemnific (did I spell that right) of a MSA. And yes, Grady County (Guthrie) is part of OKC CMSA. Actually, it should be part of OKCs MSA, because there is almost NOTHING in Guthrie so they have to come down the 30 miles or so to OKC and Edmond for shopping, services, and certainly Entertainment!
Sorry for the long message, but I wanted to chime in here because I think there was beginning to be doubts about how important OKC is to the state. It is very similar in nature that Seattle is to my state - Washington. Or Portland to Oregon, or Denver to Colorado.
Speaking of Denver, their CMSA goes alltheway to Wyoming, even tho Bolder has a MSA, Ft Collins has an MSA, CheyenneWY has an MSA (albeit very small); Denver CMSA includes all of them (except Cheyenne officially but really, everyone from Cheyenne goes down to Denver for everything, Cheyenne is like Guthrie but it is the state's capital and largest city).
They cut Denver CMSA off at Colorado Springs (I forget the county). That is some 200 miles N-S! We wont even talk about E-W (which Western KS and the whole state of CO and UT come to Denver as it is the ONLY Big city for 600 miles [then you run into OKC by the way]!).
Oklahoma City, the RENAISSANCE CITY!
