The U.S. Census counts every resident in DuPage County and throughout the United States once every 10 years.  The Census data is used to determine representation in Congress and to distribute billions in federal funds to local communities for services such as schools, roads, healthcare, and other programs.

The data you provide to the Census Bureau is highly secure, and by law cannot be shared with any other governmental or private agency.  Below is helpful  information regarding the U.S. Census:
