City of Chicago

About

There have been several blog posts about open data in Chicago (see here and here) - though there doesn't seem to be a single registry of open data.

Political/administrative boundary data sets are available at:

Datasets include:

  • Census Block
  • Census Data -- November 2004
  • Census Tracts
  • City Boundary
  • Citywide Wards Map
  • Community Areas
  • IL House
  • IL Senate
  • Surrounding Municipalities
  • Neighborhoods
  • Precincts
  • TIFS 2008
  • US Congress
  • Zipcodes

Openness

Assume this is intended to be open, but no information found on whether or not data can legally be reused.
