2020 Census Maps: California’s Hard-to-Count Communities

Much is at stake for California in the 2020 Census. The state’s political representation depends on an accurate count, as does the distribution of billions in federal funds for critical public investments and services. Many California communities are vulnerable: about 75 percent of residents are considered hard to count.

These interactive maps highlight hard-to-count communities across the state. The “likelihood of no response” category offers an overall assessment, while the other categories—undercounted racial/ethnic groups, noncitizens, young children, housing, and internet access—identify underlying characteristics that can help guide outreach efforts. The maps provide information for counties, congressional districts, state senate and assembly districts, and census tracts.
