From yesterday's NY Times:
New York’s Gap Between Rich and Poor Is Nation’s Widest, Census Says
Surprise, surprise: New York has the widest gap between the rich and poor of any major metropolitan area.
In Manhattan, the disparity was especially wide. The wealthiest 20 percent of Manhattanites made nearly 40 times more than the poorest 20 percent — $351,333, on average, compared with $8,855, a bigger gap than in any other county.
Over all, the poverty rate in the city was 19.1 percent, about where it had been for the previous six years, which meant that about one in five New Yorkers lived below the official poverty line, defined by the federal government as $20,650 for a family of four.
Median income in the city barely budged, to $46,480 in 2006, statistically only slightly higher than the adjusted $44,835 recorded the year before.
I suppose you could try to look at the bright side of this: New York is an incredibly diverse place-- unlike some suburban areas where the population and income level are very homogeneous, there are places here where you can have millionaires living next door to people who are at the poverty line. Though chances are they aren't inviting each other over for dinner.
