This report provides updated regional estimates of the number of non-elderly uninsured Californians in 2017. The estimates build on prior versions of the California Simulation of Insurance Markets (CalSIM) microsimulation model and incorporate updated survey and administrative data.

Findings: About 3 million Californians will remain uninsured in 2017, according to preliminary estimates from this report. 

This new data book breaks out estimates of the remaining uninsured by eligibility category and by Covered California region. The majority of those projected to remain uninsured in California are not eligible for Medi-Cal or Covered California due to their immigration status. Just under 25% are eligible for either Medi-Cal or subsidized coverage through Covered California. The remaining 18% are eligible for Covered California but would not receive subsidies.
