I’ve written in the past about my skepticism regarding the 2010 census when it comes to Brooklyn in general and Williamsburg/Greenpoint in particular. For an illustration of exactly how wack the 2010 census is, look no further the data on new housing units since 2000. Between 2000 and 2009, CB1 (Williamsburg and Greenpoint) added just 11,900 new housing units. In addition to that, about 5,000 housing units were renovated – a number that includes many conversions from non-residential use, and thus a further addition of (legal) housing units. Using the city’s standard EIS methodology and assuming an average of 2.2 people per housing unit (a conservative number historically for CB1), that equates to a population increase of at least 30,000 to 35,000.

The census says we added 12,745 people during that period.
