I’ve lived in New York seventeen years but I still don’t really know where Greenwich Village starts and ends. Neither, apparently, do most people, as you can see in the map above. That’s a composite of the Village’s neighborhood borders as drawn by visitors to DNAinfo’s neighborhood mapping project.

The site collected thousands of drawings from New Yorkers of how they define the area where they live and created fascinating visualizations of every neighborhood. What it shows is that these boundaries are very fluid, something that’s even more apparent when you compare the drawings from Village residents who have lived there more than twenty years (below) to those who have lived there any amount of time (above).

You can see and play with the data across all of New York City’s neighborhoods at visualizations.dnainfo.com.
