The California Census Office has compiled the resources below to make it easier for partners and stakeholders to join the State’s efforts. Help spread the message about the importance of participating in the 2020 Census to communities throughout California.

California faces the greatest barriers in the nation to ensure an accurate count and thus receive a fair share of federal funding and Congressional representation. That’s why state leaders are devoting significant funding to the California Census Office’s strategic outreach and communication campaign, an effort will seek to reach more than 13.5 million households in California to raise awareness of the 2020 Census and motivate the hardest-to-count Californians to respond. Those that are considered hard-to-count (HTC) are least likely to respond to the Census questionnaire without specialized outreach and assistance.

The California Hard-to-Count Interactive Map

HTC Interactive map with logoMany California residents live in areas that, based on demographic, socioeconomic and housing characteristics, may be hard to count in the 2020 Census.

The California Census Office has created this interactive map that shows California census tracts and block groups shaded by their California Hard-to-Count Index, a metric that incorporates 14 variables correlated with an area being difficult to enumerate.

Census tracts and block groups with higher CA-HTC indexes likely will pose significant challenges to enumerate in 2020, while tracts and block groups with lower indexes should be easier to count.

Accountability, Transparency and Reporting

The Census Office is committed to transparent operations. As relevant information becomes available, Census Office staff routinely provide updates to local and Tribal governments, the Census Bureau, key partners, and other stakeholders through regular meetings and reports. The Census Office regularly updates the state Census website with critical information, including funding plans, applicable timelines, staffing information and other operational information.

The Office will continue to share financial information, such as expenditures, encumbrances, operational plans and accomplishments via its website and quarterly reports to the Legislature and Governor’s Office. In addition, the Census Office will collaborate with the Office of State Audits and Evaluations for oversight of financial contracts and Census Office resource utilization.
