The Parcel 2013 feature contains tax parcel polygons for the 2013 property tax assessment at the County. This feature reflects tax parcel polygons as they existed from 1/1/2013 through 12/31/2013. Each parcel is uniquely identified with a Property Index Number (PIN).

The Street Midlines in this feature class represent the interpreted midline between the compiled edges of pavement. Unimproved rights-of-way are also included in this database.

The official statements below provide detailed information about the outstanding bonds issued by the County. The full faith and credit of the County is pledged to the punctual payment of the principal and of interest on General Obligation bonds, with a pledge of home rule sales tax revenues securing the associated sales tax revenue bond issues.

This data set includes property locations and attached spatial data for all Cook County parcels. Spatial matching was based on parcel centroids. Older properties may be missing latitude and longitude data because they are not contained in the most recent parcel shape layer. Brand new properties may be missing a mailing/property address because the postal service has not yet assigned the property an address. Data attached to each PIN is the most recent available. For example, Census tract data is drawn from the 2014-2018 5-year American Community Survey.
