3. CHIS History & Aims Conceived out of need for better data on health insurance coverage in California First fielded in 2001 and conducted as a biennial survey through 2009 and continuously beginning in 2011-2012 2013/2014 data to be released in August 2015 Currently in the field for CHIS 2015/2016 Specific Aims: To support decision making at the local level and statewide in public health and health care To understand and measure health needs and disparities in California — characterized by ethnic, geographic, and social class diversity

4. CHIS introduction • The California Health Interview Survey (CHIS) is the most comprehensive source of health data on California’s diverse population and the largest state health survey in the U.S. • 50,000 Californians (adults, teens, and children) are interviewed by CHIS. • Data from CHIS is used by policymakers, health departments, hospitals, CBOs, and researchers in public health and health care.

5. Methods: how is CHIS done? • CHIS has been collected every other year since 2001 • Became a continuous survey in 2011 • Random digit dial (RDD) telephone survey designed to provide statistically reliable estimates. 1. At the local level for counties (adults) and statewide 2. For major racial/ethnic groups and many ethnic subgroups • Participants are chosen at random. • One adult from each household, plus one teen and one child if available. • CHIS is funded by federal and state health agencies, California and national foundations, and others.

6. Methods: How is CHIS Done? • 56 total geographically defined strata • 2 counties with sub-county strata • Los Angeles: 8 Service Planning Areas (SPAs) • San Diego: 6 Health Regions • 39 individual county strata (excluding LA and San Diego) • 3 grouped county strata containing the 17 smallest counties (by population)

7. Methods: How is CHIS Done? • Two separate RDD samples: 1. Landline telephone numbers at stratum level (56 strata) 2. Cellular telephone numbers (since CHIS 2007) at “region” level (7 regions) • Ethnic oversamples • Koreans and Vietnamese oversampled in each CHIS cycle through: • Geographic targeting • Surname list sample • Interviews conducted in 7 languages: English, Spanish, Chinese (Cantonese and Mandarin), Korean, Vietnamese, and Tagalog • Beginning 2015, cell phone sample will be 50% of sampling frame

26. Future Immigration Measures on CHIS • New questions have been added to the adult survey and are currently in data collection for CHIS 2015-2016. • In what year did you become naturalized? • Tell me if you are currently here on any of the following: a tourist visa, a student visa, a work visa or permit, or another document which permits you to stay in the U.S. for a limited amount of time? • Was this visa or permit through Deferred Action for Childhood Arrivals or “DACA” or Deferred Action for Parental Accountability or “DAPA”? • Is this visa or document still valid or has it expired?
