"If you look at the official poverty measure in California, we’re about average with the rest of the country," Mayes said. "But if you use the supplemental poverty measure, we are in the lead. We have the highest poverty rate in the nation -- higher than New Mexico, higher than any of the southern states, Louisiana, Alabama, higher than Idaho."

"I think Assemblymember Mayes’ comments are accurate," said Chris Hoene, executive director of the left-leaning California Budget Policy Center, which has closely studied poverty in the state.
Hoene said the high poverty rate in the supplemental report is driven by California’s stratospheric housing costs. He added that use of the supplemental measure has gained wide acceptance among researchers.
"I think in most quarters, that’s not disputed," he said.
Marybeth Mattingly, a researcher at the Stanford Center on Poverty and Inequality added by email: "Basically, yes, this statement is (sadly) accurate."
