The City of Chicago's Data Portal is dedicated to promoting access to government data and encouraging the development of creative tools to engage and serve Chicago's diverse community. The site hosts over 600 datasets presented in easy-to-use formats about City departments, services, facilities and performance. The catalog presented below lists datasets alphabetically and links back to each set on the Portal.

Those interested in building applications, or creating interesting visualizations that use City data, should check out the following resources:
