Welcome to the 2020 Census Office

The State of Illinois official website for 2020 Census.

Governor Pritzker and his administration are committed to ensuring that Illinoisans get their fair share of federal resources and Congressional representation by encouraging the full participation of all Illinoisans in the 2020 Census. 

The U.S. Constitution requires that every person living in the United States is counted every ten years for the purpose of ensuring fair representation and distribution of resources. The U.S. Census Bureau will carry out the census next spring, and Census Day is on April 1, 2020. The decennial census provides foundational information that will be used to make policy decisions for ten years. Given how much is at stake in Illinois, the Illinois General Assembly appropriated $29 million of General Revenue Funds for census outreach, education and mobilization. That work is being launched now to prepare for a fair and accurate count.

The Illinois Department of Human Services (IDHS) administered a statewide Notice of Funding Opportunity (NOFO) to issue grants to community providers and local governments to encourage full participation in the 2020 Census. Efforts focus on populations and geographies deemed "Hard to Count" by the U.S. Census Bureau. "Hard to Count" areas are defined as a geography where the self-response rate in the 2010 decennial census was 73% or less. There are also populations that have been historically undercounted, including young children, immigrants, low-income households, people of color and rural residents to name a few.

What is at Stake

An accurate count of Illinois' population is essential to ensure that the State receives the funding it needs to properly care for its residents and provide critical services and programs. In 2015, Illinois received $19,738,866,367, or approximately $1,535 per capita, in federal assistance for sixteen programs. The failure to count every Illinois resident would have devastating effects on Illinois' ability to meet the needs of its residents.  Even a one-percent undercount would result in the State losing $19,557,435 per year for a decade, resulting in a total loss of $195,574,350.

As important, the number of seats Illinois has in the U.S. House of Representatives for the next 10 years will be determined by the census count in 2020. Illinoisans deserve proportionate representation in the U.S. Congress, and a fair and accurate census count is how we ensure that happens.

Finally, state and local governments will use census data to redraw electoral maps in order to align with the principle "one person, one vote". Our own state's legislative maps will be re-drawn, and this will impact the size and make-up of each district in the Illinois General Assembly.

We hope you visit this site often, as we will be adding information regularly and sharing important local and national census news.
