Census 2020 Explained California Census 2020 is a statewide outreach and awareness campaign designed to ensure an accurate and complete count of all California residents in the upcoming federal Census 2020. In support of the overall census outreach strategy, the Governor created an advisory committee called the California Complete Count Committee. The California Complete Count Committee is a panel of community leaders from across the state working to implement strategies that will increase the count of all Californians, especially those that are hard to count. Why is it important to have an accurate count of California’s population? Every 10 years, the U.S. Census counts every resident in the nation. A complete and accurate count of California’s population is essential to the state because the data collected by the Census determines the number of seats each state has in the U.S. House of Representatives and is also used to distribute billions of dollars in federal funds to local communities. More than 70 federal programs that benefit California, including education, health, and human services, use Census numbers as part of their funding formulas.
