There might be good reasons to use that breakdown, but I still think referring to people with a household income of $65K as "upper class" is misleading. There's also something a bit strange with this breakdown. The top 20 percent of households made more than $91,705 [0][1] in 2007. $65K appears to be the top 20 percent of census tracts. That doesn't seem right, though, because you wouldn't expect 20 percent of the population to come from 20 percent of the tracts, unless they're exactly the same size (which tracts are not), so maybe I made a mistake in interpretation.
