Fact Sheet
Many Californians struggle to afford job-based coverage, especially family coverage. Under the original Affordable Care Act (ACA) regulations, workers whose coverage for themselves only cost more than 9.61% of household income (in 2022) could receive subsidies to enroll in Marketplace coverage, along with their family members. However, if coverage for the worker only was affordable no one in the family was eligible for subsidies, even if the cost of family coverage was unaffordable.

Policy Brief
Since the enactment of the Affordable Care Act (ACA) in 2010, California has reduced the number of uninsured from 6.5 million in 2011 to a projected 2.99 million in 2023. This dramatic increase in the number of Californians with health insurance coverage was the result of policy choices at both the state and federal levels to not simply implement the ACA but to build on it, including through early implementation, expansion of Medi-Cal, and improvements in subsidies.

Policy Brief
Since the Affordable Care Act (ACA) was enacted in 2010, California has successfully implemented the law and built upon its provisions by extending affordable coverage to even more California residents. The proposal to expand Medi-Cal to all low-income residents ages 26 to 49 regardless of immigration status would cover close to 700,000 Californians and result in the largest decrease in the uninsured rate since the major insurance reforms in the ACA were implemented in 2014.

According to the Californa Health Interview Survey (CHIS), in the years leading up to the Affordable Care Act (ACA), the uninsured rate among Californians was approximately 14 percent. Implementation of the ACA, along with legislative initiatives and support under Governor Gavin Newsom, dramatically reduced the rate of uninsured to 6 percent by 202, with approximately 2.3 million remaining uninsured in the state.

Policy Note
The COVID-19 pandemic has further highlighted the importance of ensuring that all Californians have health coverage. As the state explores options for the unified financing of health care, policymakers are simultaneously working toward universal coverage under the current system.

Research Report
This study identifies whether culturally based differences in perceptions of health resulted in differences in ambulatory care use among the elderly.  Methods: The authors conducted stratified Poisson regressions on data from a 1992 survey of older Koreans and Whites in Los Angeles County. The models included measures of demographics, health, functioning, income, insurance, social support, and culture (perceptions of health or other beliefs).  Results: Descriptive findings showed older Koreans

Research Report
About 3 million Californians will remain uninsured in 2017, according to preliminary estimates from this report. The preliminary results were found using the California Simulation of Insurance Markets (CalSIM) model version 2.0. This new data book breaks out estimates of the remaining uninsured by eligibility category and by Covered California region.

Research Report
The Affordable Care Act (ACA) has expanded health coverage to millions of Californians and has improved coverage for millions more, but between 2.7 and 3.4 million Californians under age 65 are predicted to still remain uninsured by 2019, after the ACA is fully implemented. Of those predicted to remain uninsured, almost half — between 1.4 and 1.5 million — are ineligible for federal coverage options due to their immigration status.
