Median Income in the 5 Boroughs.

So, it turns out that Wikipedia has already covered this.  It isn't clear, but I believe these numbers are from the 2010 census.  I was wrong about Queen's median income:

Area	Median House- hold Income	Mean House- hold Income	Percent- age in Poverty
Bronx	$34,156	$46,298	27.1%
Brooklyn	$41,406	$60,020	21.9%
Manhattan	$64,217	$121,549	17.6%
New York City	$48,631	$75,809	18.5%
New York State	$53,514	$77,865	13.7%
Queens	$53,171	$67,027	12.0%
Staten Island	$66,985	$81,498	9.8%
United States	$50,140	$69,193	13.0%

I highly suggest reading the whole income section from this Wikipieda page.
