Ward boundaries in Chicago from May 2015 to May 2023, corresponding to the dates when a new City Council is sworn in, based on the immediately preceding elections. Neither this description nor the dataset should be relied upon in situations where legal precision is required. The data can be viewed on the Chicago Data Portal with a web browser. However, to view or use the files outside of a web browser, you will need to use compression software and special GIS software, such as ESRI ArcGIS (shapefile) or Google Earth (KML or KMZ).

This is the ward map that preceded the 1992 map. The file was generated largely from voting district boundaries (which are numbered by ward) and may consequently contain some minor errors. Christopher Siciliano did a considerable amount of cleaning up of this file. Name of the shapefile is ward1986.shp

Selected variables from the most recent 5 year ACS Community Survey (Released 2023) aggregated by Ward. Additional years will be added as they become available. The underlying algorithm to create the dataset calculates the percent of a census tract that falls within the boundaries of a given ward. Given that census tracts and ward boundaries are not aligned, these figures should be considered an estimate. Total Population in this Dataset: 2,649,803 Total Population of Chicago reported by ACS 2023: 2,664,452 % Difference: %-0.55 There are different approaches in common use for displaying Hispanic or Latino population counts. In this dataset, following the approach taken by the Census Bureau, a person who identifies as Hispanic or Latino will also be counted in the race category with which they identify. However, again following the Census Bureau data, there is also a column for White Not Hispanic or Latino. The City of Chicago is actively soliciting community input on how best to represent race, ethnicity, and related concepts in its data and policy. Every dataset, including this one, has a "Contact dataset owner" link in the Actions menu. You can use it to offer any input you wish to share or to indicate if you would be interested in participating in live discussions the City may host.

This map was current from 1992 until 1998, when litigation forced some boundary changes. This file contains accurate straight lines in some places where the corresponding street files have inaccurate crooked lines. The author of this boundary file is Christopher Siciliano. It was edited very slightly in 2001 by George Stachokas.
