A note on ZIP codes

ZIP codes are postal delivery routes, not civic boundaries, and they do not line up with Chicago's 77 community areas or 50 wards. Some city datasets — including crime and building permits — carry no usable ZIP field at all. For those, use the neighborhood and ward pages, which follow the geography the city actually tags its records with.
