Your response to the 2020 Census is important. Census results help determine how billions of dollars in federal funding flow into states and communities each year. The census provides critical data that lawmakers, business owners, teachers, and many others use to provide daily services, products, and support for you and your community. This can include health clinics, fire departments, schools, roads and highways. The results also determine how many seats in Congress each state gets. The Census is mandated by the U.S. Constitution in Article 1, Section 2: The U.S. has counted its population every 10 years since 1790.
