Per capita income data are from the United States Department of Commerce, Bureau of Economic Analysis (BEA), last updated on February 5, 2026 with new statistics for 2024 and revised statistics for 2020-2023. Values are calculated using personal income data and population figures from the U.S. Census Bureau mid-year population estimates. Silicon Valley data include Santa Clara and San Mateo counties. All per capita income values have been inflation-adjusted and are reported in 2024 dollars using the Bay Area consumer price index for all urban consumers from the Bureau of Labor Statistics for Silicon Valley and San Francisco data, the California consumer price index for all urban consumers from the California Department of Finance, and the U.S. city average consumer price index for all urban consumers from the Bureau of Labor Statistics. The personal per capita income for the United States is derived from state and regional data (as opposed to National Income and Product Accounts data), which include all persons who reside in a state, regardless of the duration of residence, except for foreign nationals employed by their home governments in the United States. State personal income includes the income of resident foreign nationals working in the United States—including migrant workers—regardless of length of residency. It excludes the portion of income earned abroad by U.S. citizens living abroad for less than a year. It also excludes the earnings of federal civilian and military personnel stationed abroad and the property income received by the federal pension plans of those workers.

Personal income is defined as the sum of wage and salary disbursements (including stock options), supplements to wages and salaries, proprietors’ income, dividends, interest, rental income, and personal current transfer receipts, less contributions for government social insurance.
