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

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.

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.

Ward precincts, which function as local election districts to determine the polling places for voters, based on their addresses. Precincts are based on U.S. Census Bureau blocks.

This is the ward map for Chicago that was in effect between 1998 and early 2003. The file was derived from the Tiger 1998 voting district file. George Stachokas has edited the file, altering some of the boundaries to make them more closely resemble the boundaries shown in the city of Chicago's published ward maps. Name of the shapefile is ward1998.shp

This file corrects several problems in the original TIGER/line files, notably the inclusion of parts of Lake Michigan within the city limits, and the numerous irregularities that are a function of the way the TIGER/line files were created. This file will consequently not line up with TIGER/line streets or tracts; it will line up with the 1992 ward boundary file. Its author is Christopher Siciliano.
