Using city limits like this always bothers me. Boston may be the 24th largest city by population, but that's only due to its constricted land area and much of its urban population is found within the inner suburbs. Even though it's the 24th largest US city by population, it's around 10/11 for metro, and a substantially larger urban area than the following "bigger" cities: Phoenix, San Antonio, San Diego, San Jose, Austin, Jacksonville, Fort Worth, Columbus, Indianapolis, Charlotte, Seattle, Denver, Oklahoma City, Nashville, and El Paso.
If Boston annexed its suburbs to match the square miles of some of these other cities it would be the 5th or 6th largest city in the US. That's its real weight, not just a "700,000 person city."
I've cited this factoid before on AB--and ultimately, that's all it is, a factoid--but I still think it's marvelously illustrative in terms of how regional planning in E. Mass. is absolutely crippled by how many independent municipalities that "should be Boston," given their density characteristics, are not.
The farthest point in Readville is exactly 10.0 miles from City Hall on a line. There are
23 independent municipalities, the Town/City Halls of which are equal or less than the distance to Boston City Hall, as compared to Readville,
a neighborhood of Boston.
Quincy, Milton, Dedham, Brookline, Newton, Cambridge, Watertown, Waltham, Somerville, Belmont, Winthrop, Revere, Chelsea, Malden, Medford, Arlington, Winchester, Melrose, Woburn, Stoneham, Lynn, Saugus, Winthrop
Our invention of "New England-style" small-town democracy/governance is surely a wonderful thing, but, again, for the great regional issues--homelessness, housing, climate change, transit, etc.--it is utterly devastating.
