Rats and obnoxious parties are two iconic big-city problems, but these irritants, like income, are not evenly distributed across New York City. The map above—inspired by this similar project from The Furman Center—examines two-and-a-half years of complaints to the city's 311 phone line, focusing on the calls classified as either "vermin" or "loud party/music." That's over 260,000 complaints in total, split by ZIP code.

The complaints have been color-coded to show which problem prevails in which neighborhoods. Red indicates more complaints about parties, blue means more complaints about vermin, and the size of the hexagon is proportional to the total number of complaints in these two categories. Overall, New York had 57 percent more vermin complaints than party complaints.
