About the Census

The goal of the U.S. Census is to count every person living in the U. S. once, only once, and in the right place.

Your response is important and directly impacts Coralville and Johnson County. The census is much more than just a head count. It helps determine where to build new schools, hospitals, and businesses; and how congressional seats are apportioned. It also helps us see how our communities have changed over time. That’s why an accurate count is so important.

What you need to know about the 2020 Census

Why it’s important

Responding to the census helps Coralville and Johnson County get funding and helps businesses make data-driven decisions that grow the economy.
  • Census data impact our daily lives, informing important decisions about funding for services and infrastructure in our community, including health care, senior centers, jobs, political representation, roads, schools, and businesses.
  • It impacts our community. The distribution of more than $675 billion in federal funds, grants and support to states, counties and communities are based on the census data. That money is spent on schools, hospitals, roads, public works and other vital programs.
  • Every 10 years, the results of the census are used to reapportion the House of Representatives, determining how many seats each state gets.
  • It’s in the constitution. The U. S. Constitution mandates that everyone in the country be counted every 10 years. The first census was in 1790.
  • Redistricting. After each decade’s census, state officials redraw the boundaries of the congressional and state legislative districts in their states to account for populations shifts.
  • It’s your civic duty: a way to participate in our democracy and say “I count.”
  • Local government officials use the census to ensure public safety and plan new schools and hospitals.
  • Businesses use Census Bureau data to decide where to build office, stores and factories, and these create jobs.
  • Real estate developers and city planners use the census to plan new homes and improve neighborhoods.
