I'm trying to get a grip on where metropolitan areas begin and end. Census maps are county based and aren't very useful. So, I am wondering if anyone would care to define, geographically, their own metro area. For an example, I'll use the Bay Area.
This is probably broader than most people's ideas (well, definitely broader), but for me the northern California metropolis known as the Bay Area starts at the bottom of the Monterey Peninsula mini-area and tops out in Wine Country, I generally say Santa Rosa area. To the east are several corridors, on which I terminate the area at the following cities - Brentwood, Green Valley, San Benito, Livermore. To the West, of course, is the ocean.
If that makes any sense that's more or less what I'm looking for. Arguing with me about that definition is an acceptable use of this thread, but I'd really like to know what those in major cities like Boston, NYC, LA, Philadelphia, Detroit, DC etc. feel are the edges of their areas (although I am aware that doing this in the Northeast corridor may be difficult). Thanks,
