Covered California premiums for 2019 will rise by an average of 8.7% statewide. The increases vary by region of the state; the region including Santa Barbara County is right on the average at 8.7%.
The increase is about double what it would have been if Congress had not repealed the individual mandate last year. Further increases as a result of that repeal may occur in the future.
