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. Some boundaries were altered to more closely resemble the boundaries shown in the city of Chicago's published ward maps.

ESRI shapefiles created at the University of Chicago Library Map Collection. Created during the 1990s from contemporary TIGER files. Files may have problems associated with TIGER files of the period. Attribute authorship to the Map Collection, University of Chicago Library and any other personal authors named in text.

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.

The Chicago Elections Project is a digital history collaboration working to expand access and provide interpretation on the electoral and political history of the city. The Chicago Elections Project is a large-scale digitization and visualization project that will allow the public, journalists, and researchers to understand the political history of the city in new ways. It will enable the telling of stories about the neighborhood and city-wide electoral contests that shaped public policy in Chicago and Illinois over more than a century.

For more information, visit the Chicago Elections Project website: http://www.chicagoelectionsproject.com

The data in the Chicago Elections Project was created by the Chicago Board of Elections in the course of administering the city’s elections. The collection presented here seeks to make the digitized archival materials and data visualizations accessible for further and future public research. These materials include images of the city’s ledgers which contain tabulated election results (.jpg files); the project’s excel spreadsheets that transcribe election results from the city’s ledgers (.xlxs files); images of the Chicago Board of Elections’ ward and precinct maps (.jpg files); and digital map materials created from these images (shapefile bundles). The files are organized first by year and then election type; see the ReadMe file for a detailed outline and description of files included in the data collection.

Since 1923, there have been 50 wards in the City of Chicago. Each ward consists of a variety of precincts. From 1889 to 1923, there were 35 wards.
