Welcome to State of Illinois Open Data Portal!

Illinois Open Data Portal lets you find data across state, find facts about your state, lets you create maps and graphs, and lets you freely download the data for your own analysis. Many of these datasets are updated daily, and some even more often.

On March 10, 2014, the Illinois General Assembly unanimously passed PA 98-0627, a bill introduced by the Governor's Office and intended to increase transparency, accountability and savings in government by establishing a new State Open Operating Standard.

On December 10, 2018 HB1168 was enacted extending the repeal date for the Open Operating Standards Act to January 21, 2021.

We are excited to provide this service and are working hard to make it more useful. New to the open data portal? Navigate over to the manual. If you have any questions or feedback, email us.
