CHIS Annual Data Release

High rates of food insecurity, hate incidents, and difficulties accessing health care were at the forefront of issues that plagued Californians in 2022, according to the annual California Health Interview Survey (CHIS) data released on October 4, 2023.

Food insecurity on the rise
The data revealed that a growing number of low-income Californian adults (earning less than 200% of the federal poverty level) struggled to access nutritious and affordable food: 44% were not able to afford enough food in 2022, up from 35.8% in 2020. 

The most significant increase between 2020 and 2022 occurred among working-age adults, jumping 11 percentage points among 18–24 year olds to 47.7%; 8.6 percentage points among 25–39 year olds to 51.4%; and 12.4 percentage points among 40–64  year olds to 48%. Latinx adults experienced the highest increase in food insecurity with a 9.6 percentage point increase to 47%. However, adults who identify with two or more races and Black or African American adults had among the highest overall rates of food insecurity in 2022: 49.9% and 48.6%, respectively.

Brand new questions on hate incidents
The 2022 survey added new and expanded questions on Californians’ experiences with hate crimes or incidents. While more than 1 in 9 (11.7%)  adults said they have ever been a victim of a hate crime or incident, the rate among Black or African American adults was 1 in 4 (26.2%) — four times as high as the 6.3% for white adults. The figure was 17.4% for adults who identify with two or more races, 15.6% for Asian adults, and 13.5% for Latinx adults.

Health insurance coverage hit an all-time high, but access to care impacts many
A bright spot in the data was that the proportion of Californians who had health insurance in 2022 reached 94.8% — the highest rate recorded by CHIS. Latinx adults have the lowest health coverage  rates, but saw the most significant increase in coverage: from 86% to 89.4%.

However, difficulty accessing care was a concern among many, with more than 1 in 5 (22.4%) adults indicating they were never able to get a doctor’s appointment within two days when they tried, up from 12.3% in 2020. Similarly, one-third (33.3%) of adults who needed mental health care said difficulty getting an appointment was the reason they didn’t get the help they needed in 2022, up from 24.4% in 2021.

Pattern of higher mental health needs 
About 1 in 6 (16.4%) adults reported in 2022 that they likely had serious psychological distress (SPD) in the past year, similar to 2021 (17%) and higher than in 2019 (13%) and 2020 (12.2%). 

LGBT adults had significantly higher rates of SPD: 61.6% of transgender or gender nonconforming adults; 46.9% of bisexual adults; and 29.7% of gay, lesbian, or homosexual adults experienced SPD compared to 13.6% of straight or heterosexual adults and 15.8% of cisgender adults. Nearly 1 in 5 adults in 2022 (18.9%) and 2021 (19.1%) said they experienced suicide ideation within the past 12 months, up from 12.2% in 2020.

COVID-19 vaccination status and views
Among teens who were partially vaccinated or not vaccinated, 21% said the reason for not being fully vaccinated is because their parents didn’t want them to get the vaccine and 27.6% said it’s because they think the vaccine is unnecessary.

Nearly 1 in 3 (30.7%) adults who have had COVID-19 experienced symptoms for two months or longer (long COVID). Latinx adults (38.4%) had higher rates of long COVID compared to white adults (24.1%). 

“While the state of California is often seen as a leader in striving toward health equity, the 2022 data highlights some of the ongoing disparities that are impacting Californians’ overall well-being,” said Todd Hughes, CHIS director. “This isn’t just a collection of numbers. This is a story of Californians: their challenges, their fears, and their needs. This is the key to shaping a brighter, healthier future for all.”

CHIS Preliminary COVID-19 Estimates Dashboard

When the COVID-19 pandemic began in 2020, little was known about the virus and the broad impact — health, economic, and personal — it would have on people around the world. 

Focused on providing timely insights, the California Health Interview Survey (CHIS) quickly adapted survey operations, adding a series of COVID-19 questions to CHIS immediately and abbreviating data processing procedures to produce monthly estimates. 

From questions on COVID illness, to risk- reduction behaviors and mask use, to financial impacts such as job loss and essential worker status, CHIS provided public health departments, policymakers, legislators, and other decision makers data through the development of publicly accessible CHIS Preliminary COVID-19 Estimates dashboards.

CHIS continued to provide these monthly estimates for 2020, 2021, 2022, and 2023, and added timely questions, including experiences with long COVID; vaccination status and views on the vaccine; reasons for not getting the vaccine; and personal impacts, including various financial difficulties and unfair treatment due to race or ethnicity. The data can also be viewed by sociodemographic factors, including age, race and ethnicity, citizenship status, income level, risk factor, California region, and more to better understand the unique challenges of California’s diverse population.

In 2023, CHIS released its final set of monthly estimates, which included responses from 20,134 Californians (16,786 adults and 3,348 children and teens), from March through August 2023.

Findings from the August 2023 dashboard include:

COVID-19 vaccine status and testing

  • 1 in 3 (32%) adults said they would not get additional COVID-19 vaccine doses, even if recommended by health guidelines.
  • 23% of adults who completed the primary vaccine series for COVID-19 have not received any additional doses or boosters.
  • 47% of adults who received a positive test result for COVID-19 got their results from a self-test kit; 30% from a clinic, hospital, lab, or other testing facility; and 24% from both a testing site and a self-test kit.

Californians’ reasons for not completing the primary vaccine series for COVID-19

  • 46% of adults and 30% of teens and children thought a vaccine for COVID-19 is unnecessary.
  • 46% of adults and 45% of teens and children were worried about the side effects.
  • 37% of children and teens said their parents did not want them to get the vaccine.
  • 32% of adults didn’t believe in vaccines in general.

  • 30% of adults experienced COVID symptoms for two months or longer.
    • By income level: 46% of adults with incomes 0–99% of the federal poverty level (FPL) and 42% of adults with incomes 100–199% FPL experienced COVID-19 symptoms for two months or longer, significantly higher than adults with incomes 300% FPL and above (23%). 
    • By race and ethnicity: 44% of Latinx adults experienced COVID-19 symptoms for two months or longer, two times higher than 22% of white adults.

Personal impacts of the pandemic

data files on a variety of topics. 

PUFs, which are free and accessible to anyone via a brief application, enable researchers to customize and run their own statistical code. Files are available in various statistical programming formats — SAS and Stata.

Designed for advanced data users, PUFs include microdata files, hundreds of variables and detailed demographic information, and a data dictionary and survey questionnaire.

Researchers can apply to analyze confidential CHIS data, data-sensitive variables, and/or geocoded data through the CHIS Data Access Center (DAC). The DAC provides researchers with remote access to confidential data files in a secure, controlled environment that protects the confidentiality of respondents. 

The confidential CHIS files maintained in the DAC contain detailed geographic identifiers, complete demographic information for survey respondents, and highly sensitive information (e.g., sexual behaviors, mental health treatment) that has been specifically excluded from the freely available CHIS PUFs.

Access to confidential CHIS data requires a research application, review, and approval.
