While Columbus Circle is really only considered the roundabout located on 59th and the intersection of Broadway and 8th Ave, we decided to focus on the area known as Neighborhood Tabulation Area (NTA) MN14, which includes Lincoln Square as well:
The boundaries of MN14 stretch from 58th Street up to 74th Street, and from Central Park West to the Hudson River. This is basically the Lincoln Square neighborhood, with a little bit of Clinton included to the South and a little bit of the Upper West Side to the North. Another way to describe the neighborhood is by zip code (10023):
The two areas differ slightly, but they are more or less the same.
