This dataset reflects reported incidents of crime (with the exception of murders where data exists for each victim) that occurred in the City of Chicago from 2001 to present, minus the most recent seven days. Data is extracted from the Chicago Police Department's CLEAR (Citizen Law Enforcement Analysis and Reporting) system. In order to protect the privacy of crime victims, addresses are shown at the block level only and specific locations are not identified. Should you have questions about this dataset, you may contact the Research & Development Division of the Chicago Police Department at 312.745.6071 or RandD@chicagopolice.org.

Neighborhood polygons used by the Cook County Assessor's Office for valuation and reporting. These neighborhoods are specific to the Assessor. They are intended to represent homogenous housing submarkets, NOT Chicago community areas or municipalities. These neighborhoods were reconstructed from individual parcels using spatial buffering and simplification. The full transformation script can be found on the Assessor's GitHub.

Polygon vector map data covering city boundaries for Chicago, Illinois, containing 1 feature.

Boundary GIS (Geographic Information System) data is spatial information that delineates the geographic boundaries of specific geographic features..

This data typically includes polygons representing the outlines of these features, along with attributes such as names, codes, and other relevant information.

Boundary GIS data is used for a variety of purposes across multiple industries, including urban planning, environmental management, public health, transportation, and business analysis.

Available for viewing and sharing as a map in a Koordinates map viewer. This data is also available for export to DWG for CAD, PDF, KML, CSV, and GIS data formats, including Shapefile, MapInfo, and Geodatabase.

Map of Chicago community areas.

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 is part of a collection of 10 maps showing the location of Presbyterian Churches in relation to ethnic groups in the city of Chicago. The manuscript title is "The effects of subsity of Presbyterian Churches", by Henry Hughes Presler, and can be found at Mansueto Library, University of Chicago under the call number BX 10999. These maps have been outlined and vectorized as the originals, and points placed for location of churches as they were in the original. Call number for the maps: G4104.C6E1 1948.H6. Map Collection, Regenstein Library, University of Chicago. Drawn from Map 6 - Location of Presbyterian churches in relation to ethnic groups in the city of Chicago, by Census Tracts, 1910.

The data contains Multipolygon information for the Boroughs of Chicago used for geospatial analysis. The Coordinate Reference System is EPSG:4326 (WGS84). The file is compressed with xz.

This map shows the population density in Chicago by census tracts in 2010. Population Density is measured by people per square mile. The red shape that pops up in the map is the location of DePaul University's Department of Geography.

Use Map Area Crime to view crime near a specific location / address or draw your own polygon of interest. Shows crime counts within the visible map area. Use Crime Dashboard to view crime by geographies like CPD District, CPD Beat, Ward and Community Area. Visualize how those polygons overlap. Includes interactive graphs like time of day & day of week. Both applications allow for filtering by date and crime types. Query results can be exported as a .csv file by using a button on the Nearby Crimes widget (Map Area Crime) or lower left on the Crime Incidents widget (Crime Dashboard). Be aware popup blockers may prevent downloading.

Crime data is updated daily but with a 7-day lag from yesterday to allow the data to stabilize before it’s released to the public. Exact house numbers are not shown, and the data is not offset off the street centerline.
