California's income distribution is quite broad compared to the country's as a whole; its proportions of residents with no income and of residents with income over $100,000 are both higher than the national average. This broad distribution combined with high housing and living costs give California an abnormally high poverty rate. The Census Bureau’s Supplemental Poverty Measure, calculated by comparing household income to a locally-adjusted poverty threshold, reports that 20.7% of California's population has income insufficient for their basic needs, as compared to 12.9% for the U.S. as a whole. This calculation of income includes the benefits of California welfare programs such as food stamps and earned income tax credits — without these, the state's poverty rate would be 28%.
