Census 2020 and Special Census 2024

What is the Census?

The Census is mandated by the Constitution and conducted every 10 years by the U.S. Census Bureau. The last Census Day was April 1, 2020. 

Why is the Census Important?

Census data provides vital information for our community. 

  • It determines how many representatives each state gets in Congress and is used to redraw district boundaries. 
  • Every year, billions of dollars in federal funding go to hospitals, fire departments, emergency services, schools, roads, and other resources based on census data. 
  • Businesses use census data to determine where to open stores and what services to offer.
  • Accurate population numbers make the City eligible for more state and federal money. This helps fund City services such as street repair, public safety, and more. 
  • Census data also helps the City plan for the future.

The 2020 Census reported Warrenville's population as 13,553. But that census did not get data from several newer developments. This includes residents of Everton, Lexington Trace, Arden, Westlyn, and Riverview West. 

In 2024, the City asked the U.S. Census Bureau to conduct a Special Census. The count showed that Warrenville's population grew to 15,195. This means an extra $422,000 in annual state revenue to help us fund City services such as street repair, public safety, and more.

The 2024 Special U.S. Census also found the median age of residents is 38.4, continuing an upward rise from the 2010 census median age of 36.6 years and 2020 median age of 37.9. 

The U.S. Census reported median home value of owner-occupied housing is $266,500 in 2023 (most recent dataset available). This represents a significant increase (20%) from $221,700 reported in the 2020 Census. 

Warrenville is 5.6 square miles with 42.5% residential land, 14% commercial/industrial land, 12% open space, 7.5% undeveloped area, 4% institutional, and 20% transportation and tax-exempt land.

The City’s updated population data from the 2024 Special Census will be listed under a Special Census date of June 1, 2024.
