Census Information

2020 Census LogoThe Village of Tinley Park will take part in the 2020 United States Census, which officially begins with National Census Day on April 1, 2020. The data collected helps determine the number of seats Illinois has in the U.S. House of Representatives and the amount of federal funds received for such things as schools, senior centers and public works projects. It also is the basis for many state revenue payments, such as income tax and motor fuel fax.

The last census, held on April 1, 2010, determined the population of Tinley Park was 56,703.

The Clerk's Office coordinates both the decennial and special census.

NOTICE: Due to the COVID-19 pandemic, the U.S. Census Bureau has announced an extended suspension of the 2020 Census field operations until June 1. The Bureau also asked Congress to provide a 120-calendar day extension to the deadline to deliver final counts to the White House and Congress. This deadline extension request will help ensure that Illinois and all other states are accurately counted. The Village will update residents on the status of the Census as more information becomes available.

How the 2020 Census will invite everyone to respond
Every household will have the option of responding online, by mail or by phone. Nearly every household will receive an invitation to participate in the 2020 Census from either a postal worker or a census worker. Learn more by reading this handout


Overall Timeline (2020-2021)
Counting every person living in the United States is a massive undertaking, and efforts begin years in advance. Here's a look at some of the key dates along the way.


  • January 21: The U.S. Census Bureau starts counting the population in remote Alaska. The count officially begins in the rural Alaskan village of Toksook Bay.
  • March 12 to 20: Households will begin receiving official Census Bureau mail with detailed information on how to respond to the 2020 Census online, by phone or by mail.
  • March 30 to April 1: The Census Bureau will count people who are experiencing homelessness over these three days. As part of this process, the Census Bureau counts people in shelters, at soup kitchens and mobile food vans, on the streets, and at non-sheltered, outdoor locations such as tent encampments.
  • April 1: Census Day is observed nationwide. By this date, every home will receive an invitation to participate in the 2020 Census. Once the invitation arrives, you should respond for your home in one of three ways: online, by phone, or by mail. When you respond to the census, you'll tell the Census Bureau where you live as of April 1, 2020.
  • April: Census takers will begin visiting college students who live on campus, people living in senior centers, and others who live among large groups of people. Census takers also begin conducting quality check interviews to help ensure an accurate count.
  • May to July: Census takers will begin visiting homes that haven't responded to the 2020 Census to help make sure everyone is counted.
  • December: The Census Bureau will deliver apportionment counts to the President and Congress as required by law.


  • March 31: By this date, the Census Bureau will send redistricting counts to states. This information is used to redraw legislative districts based on population changes.
