Government Maps of Chicago in the 1920s, 1930s, and 1940s

During the 1920s, 1930s, and 1940s, there was a slow growth in the planning role of municipal governments in many large American cities, including Chicago. Cartographic materials of various sorts were one of the byproducts of this growth. This Web page provides access to some government maps of Chicago from this period that are held at the University of Chicago Library's Map Collection.

Many of these maps were compiled to assist in the implementation of particular programs. In 1922, for example, the Chicago Zoning Commission, in order to facilitate the creation of Chicago's first zoning law, compiled the first land-use map of Chicago. In the 1930s, government agencies, having acquired a mandate from the New Deal to try to alleviate urban poverty, produced maps that showed the geography of substandard housing, redlined areas, population loss, and relief distribution. As World War II began to draw to a close, the Chicago Plan Commission compiled maps in which major postwar planning efforts were proposed, and in 1946 it published the first detailed land use plan for Chicago. Many features included in on this map--certain highways and rail lines, for example--not to mention a population of 3.8 million in 1965--never quite came to pass, but the postwar city of freeways, new government-built rapid-transit lines, and large-scale urban renewal was sketched out in detail for the first time.

Other government maps from the 1920s, 1930s, and 1940s were essentially descriptive, for example, the Chicago Regional Planning Association's maps of industrial employees, subdivided land, and rail commutation time. Other "descriptive" maps focused on the work of long-existing government agencies, for example, the Sanitary Commission, the U.S. Army Corps of Engineers, the Chicago Park District, and the Cook County Forest Preserve District. Late in the 1920s, the U.S. Geological Survey, in conjunction with the Illinois Geological Survey, produced prototypes of its new 7.5 minute 1:24,000 series of topographic maps for a large part of northeastern Illinois. These maps differed from what would become the standard 7.5 minute sheets in showing individual buildings, at least in a stylized form, even in urban areas. Thus, the 1928-1929 set of USGS topographic maps of the Chicago area gives an extraordinary sense of the texture of the built environment that later editions do not.

We acknowledge that many of the maps linked on this Web page, compiled for internal agency use, are not cartographic masterpieces. Some are rather difficult to read, and we have been unable to locate a completely clear legend for the land use set. Nonetheless, these maps contain information that exists in no other form.

The maps were scanned at 400 dpi using NextImage software and were saved as tiff files

You can access these files in two different ways:

[1] Click on the thumbnails below to see the files in a program called Zoomify. Zoomify breaks the original tiff files into tiny jpegs, so you can zoom in and out and move around quickly and efficiently. Zoomify requires Flash and so won't work on many mobile phones.

[2] You can also see the files through Luna. Luna, like Zoomify, allows you to zoom in and out and to move around. It also allows download of jpeg versions of the files (click "Export"). To access the Luna files, click on the "Click here for Luna version" button.

The original tiff files are also available. E-mail from the "Questions about this page?" button below.

Downloaded files are freely available for personal or scholarly use. If you use the images in a publication, we expect that you will mention that the original maps--and the files--are from the University of Chicago Library's Map Collection.

Several people contributed to the construction of this Web page. The Digital Media Laboratory let Map Collection staff use its Contex scanner, and Dale Mertes of the Digital Media Lab provided an enormous amount of assistance. Joost Dupon of the Map Collection did most of the scanning and image preparation. Bobby Butler scanned the maps added in 2014. Chris Havlin of the Map Collection, with the help of head of conservation Ann Lindsey, did some last-minute emergency repair work on certain sheets. Bridget Madden of the University of Chicago's Visual Resources Center and Charles Blair of the Library's Digital Library Development Center developed a protocol in 2015 that allows access via Luna. Bobby Butler of the Map Collection did some light editing of a few of the files, and Bobby Butler and Emily Thompson of the Map Collection changed the html on these pages to point to the Luna versions..

The 1920s, 1930s, and 1940s were of course also the period when social scientists first discovered Chicago on a large scale. See the companion Web pages, Social Scientists Map Chicago and Chicago in the 1920s and 1930s, for links to some of the cartographic products of this work.

There are some additional government maps of Chicago from this period at the Encyclopedia of Chicago Website.
