Indicator: Percent of adults who are currently uninsured, insured but had gap, and uninsured a year or more
Indicator Description: Indicators are from UCLA’s California Health Interview Survey (CHIS) Public Use File (PUF) and consequently their exploratory dashboard, AskCHIS. “Currently uninsured”, and “Insured but had gap” assess whether persons are currently experiencing, or experienced interruption in health insurance at some point in the past 12 months (CHIS PUF Variable INSANY: currently uninsured, unins. any past 12 mo.). Uninsured a year or more assesses whether persons had no insurance the entire past year (CHIS PUF Variable: UNINSANY: uninsured entire past year). Currently uninsured and uninsured a year or more are available via AskCHIS (Currently Coverage: Currently insured, Past Coverage: Any time during past year without insurance, respectively).
Note: This indicator includes individuals over the age of 64 to better comply with the baseline and target in the original 2012 LGHC taskforce report. Uninsurance percentages will be lower than other reports that exclude this population as a result, as the 65+ year population almost all have Medicare. However, coverage is still not 100% as can be seen in the bar graph, due to citizenship status or other factors.
Data Limitations: Asked of California’s residential population (adults, teens, and children), administered in English, Spanish, Chinese, Korean, Tagalog, and Vietnamese. Does not include those living in group quarters or homeless persons.
Indicator Source: UCLA’s California Health Interview Survey (CHIS) is a biennial population-based, omnibus health survey of California. It is the largest telephone survey in California and the largest state health survey in the country. Note that this indicator uses weighted data.
Indicator Calculation Methodology: Indicator constructed from responses to multiple survey questions. More information about “constructed variables” is available from the CHIS FAQs, available at https://healthpolicy.ucla.edu/chis/faq/Pages/default.aspx
Data Collection Methodology: Statewide telephone survey using a geographically stratified sample design. Estimates are weighted to Dept. of Finance demographic data (adjusted for group quarters population). More information is available at https://healthpolicy.ucla.edu/chis/design/Pages/overview.aspx
