The calculations were meant to mimic the sort of economic decision many in the region face as families grow and space gets tight.
"[W]e set out to do the math, based on an apartment and a house in the New York metropolitan area. Here's what we found: a suburban lifestyle costs about 18 percent more than living in the city. Even a house in the suburbs with a price tag substantially lower than an urban apartment will, on a monthly basis, often cost more to keep running. And then there's the higher cost of commuting from the suburbs, or the expense of buying a car (or two) and paying the insurance.
But the one big caveat in all the calculations is private schooling. If the city dwellers decide to send their children to private school - say when their children hit middle-school age - that expense would instantly make the suburbs a bargain."
