What's an urbanized area and how does it differ from MSA/CSA?!?
An urbanized area includes just the continuously built up/inhabited space that extends from the city center in all directions.
MSA includes whole counties including areas in that county that are clearly rural or small town, as LONG as a portion of that county is within the continuously built suburbia of the urbanized area.
CSA basically includes adjacent metro areas where the suburbs basically overlap, blend, yet are still considered separate spheres.
IE: Washington D.C. is separate MSA from Baltimore but are one CSA.
LA MSA does not include the Inland Empire of Riverside-San Bernardino, but CSA does.
Ann Arbor is part of the Detroit CSA, but not MSA.
Typically MSA population is not THAT much larger than urbanized area population, it simply includes the non-urban areas of the surrounding counties that are still not part of the continuously built up area, but may one day become so.
I will say that I personally don't really put a whole lot of weight on urbanized area populations.
I think the CSA is most important. Because low density suburbs/exurbs that don't have a clear separation are part of a urbanized area, but a significant small city that is somewhat urban but separated by a few farms is not part of the urbanized area doesn't get included.
I think urbanized area, combined with urbanized area population density however, is a better measure.

MSA and CSA are both determined by the percentage of people from one county commute to work in another county.
25% of the residents from one county who commute to another county are combined in a MSA.
15% of the residents from one MSA who commute to the core counties of another MSA are combined into a single CSA.

Urbanized area is based on built environment/development patterns while MSA is based on commute patterns and includes whole counties, some of which on the periphery of an MSA may have a lot of open/empty space.
This is tough for me to say this but its very hard for me to look at this and not see some sort of conspiracy at play here in regards to Philly. How in the world is the Philly and New York urban areas not combined into one? If the Trenton urban area was added to New York urban area than the Philly urban area should be added as well since the Philly urban area is continuous with the Trenton urban area.(Personally I don't understand why Trenton and Philly would be separate urban areas since Trenton is technically only 15 miles from Philly proper. Doesn't really make much sense when you use logic.)
Anyway, the main point is that Philly and New York should be a combined urban area "End Of Story"! It is clearly evident when you look at the urban areas map "that both areas are clearly continuous with each other." If this is official then it seems like yet again, the census seems to be completely delusional when it comes to the Philadelphia area. I hate to say this but the census failing to acknowledge what is clearly evident, makes me wonder if there really is a conspiracy against the Philly area.
I agree with this 100%... it clearly makes no sense. I guess they just want to keep the areas separate for some reason but how do you distinguish between New York and Philly Metros? You can't. Mercer County clearly belongs to the Philly Metro. Both the New York Metro and Philly metros are connected seamlessly to the Lehigh Valley as well...when it comes to the point where development is becoming so indistinguishable that counties switch metros depending on what decade census count you look at... it's time to combine those urban areas.
While there is a slight break in between New York and Philadelphia Metros... this map is proof of why Mercer County should be a part of the Philadelphia metro. Its just completely baffling to me as to why the Census insist on adding this area to the New York Metro...

So Cape Girardeau and Carbondale are now urbanized...interesting. The two actually aren't that far apart from each other...commuting distance almost.
