Brooklyn Paper, census data reveal that the 2 block by 10 block neighborhood bordering Carroll Gardens, Cobble Hill and Red Hook has beat out Park Slope with more same-sex couple households per capita. Of the reported 549 households, the census data claim that 11% are same-sex couple households (more than areas of Chelsea that top out at 10%). Of course, the data does not report single gay and lesbian occupants, which Chelsea would surely have more of.
It should also be noted that the area on the census map does not include the blocks between Degraw St. and the Brooklyn Battery Tunnel, which is part of the Columbia Waterfront District. This area is listed as having an additional 964 households with 0% same-sex couple households. There is an error in the data though, or at least an inaccuracy in reporting, because there are at least three same-sex couples on Union Street between Columbia and Van Brunt alone.
Inaccuracies aside, the writing is on the wall. More fabulous restaurants and boutiques will come and properties values will soar. At least until the sea level rises another 4 meters and puts the whole area underwater. But if you have no children to leave your property to, it's a great place to buy.
