Every 10 years, the United States Census Bureau conducts a population count of the entire country to determine the allocation of seats held by each state in the House of Representatives. The federal census began on April 1, 2020.

In addition to determining federal representation, the census is used to distribute federal funding to state and local governments. In California, more than 70 federal programs that benefit our residents use the Census data and population counts as part of their funding formulas, including the Community Development Block Grant Program, as well as funding for health and human services, public safety, roads, school programs and lunches, and more.

The census data is also used to redraw federal and state legislative district boundaries. For these reasons, a complete and accurate census count is essential to the well-being of our state and all Californians.

The U.S. Census Bureau will release an in-depth demographic statistics from the 2020 Census that will be used to redraw legislative voting districts on Monday, August 16, 2021. The upcoming release of the redistricting data will show how racial and ethnic makeup of neighborhoods has changed since the 2010 Census. It will also provide the first look at the demographic characteristics of the nation by state, county, and city, including: race and ethnicity; voting-age population; occupied and vacant housing units; and people living in group quarters like nursing homes, prisons, military barracks, and college dorms.

Hard to Count Index

The California Hard-to-Count Index is based on multiple demographic, housing, and socioeconomic variables correlated with an area being difficult to enumerate. Census tracts with higher indexes are likely to be places that will pose significant challenges to enumerate in 2020.
