Oh, Newsweek and your "Best High Schools" list...if only you'd point out the obvious: The "best" schools are those with the best students.
I imagine that "the list" has become something of a cash cow for Newsweek; there's simply no way they can't realize the list is of no value.
Numbers for Household income from Wikipedia pages. Chicago was split into several sections so I wasn't sure which MHI to use. (Not that it matters since the school is a selective admission, as are most, I assume; I didn't bother to check the ones that were well above the US average MHI.)
