This is the thinking that I was reffering to above -- that we have to stop looking at them as separate, where "spill overs" into another rather arbitrarily-defined area occur. There have long been residents of the Philadelphia metro who work daily in NY proper or in NY metro. And there are many people who live in NY metro and work daily in Philadelphia proper or in Philadelphia metro. This situation is likely nowhere near as high between Philly and Balt-DC metro area, nor vice-versa, yet there does exist some back and forth between Philly metro and Baltimore metro (particularly in regard to parts of Delaware and Chester county in PA. And parts of Lancaster county also feature residents who commute to Philly and Baltimore proper and to their metro regions.
It's senseless to continue this idea that population figures of the metros of the region are somehow finite. They are much more fluid.
