From The Real Deal:
While New York City has grown in the past decade, some areas have grown more than others. Staten Island posted the greatest increase in population among the five boroughs from 2000 to 2009, while Queens showed the slowest growth. In the suburbs, Long Island's Nassau County took the lead in a number of categories -- including the oldest population and the greatest percentage of homeowners -- as well as finishing second highest in household income. But perhaps the most notable change is that while the city's population grew by 3.2 percent, its total number of housing units jumped 4.6 percent.
