A drop in the state's unemployment rate to 11 percent is triggering the federal cut-off of emergency, long-term unemployment pay. At least 93,000 Californians will be affected.
The cut-off will also affect another 200,000 people who would have become eligible this year.
Under federal law, the rate of unemployment must be 10 percent higher than for the previous three years for the extended benefits to remain in each state. California's rate has been declining.
California is just one of eight states where the chronically unemployed will lose support May 12. The others are Colorado, Connecticut, Florida, Illinois, North Carolina, Pennsylvania and Texas.
