Looking for as recent as possible female to male population ratio in
New York City.  Wouldn't mind having boroughs breakdowns and age
groups as well.

Hi freakfarm,

The 2000 census is the most recent but there is a 2004 community
survey which I've posted a link to when available.  To view the age
(and other) demographics, click on the 2000 links.
