How much are Bay Area households making each year?
Income reflects the median income of households from any employment, retirement, investment or other source. Income data highlights how households fare overall in the region on an inflation-adjusted basis.

Household income is a key measurement of economic trends, the monetary well-being of Bay Area households, and the standard of living. Household income is determined not only by trends in wage levels, but also by how the overall composition of households change. In addition to salary or wage increases, household income grows when additional household members join the ranks of workers – which often aligns with times of economic prosperity, just as it typically shrinks when household members retire from the workforce.

Regional Performance
Median income growth for a typical Bay Area household has been relatively stagnant over time.
Household incomes have risen and fallen in sync with the expansion and contraction of the region’s economy over the past four decades. In the last decade, however, incomes have remained remarkably close to an inflation-adjusted average of $93,000 per household, as measured in 2017 dollars. 

Historical Trend for Percent Change in Median Income

Regional Distribution
The gap between rich and poor continues to widen.

While the trend for regional median income seems to indicate stable household incomes over time, a different story is told when examining income trends by percentile. In fact, the income gap between the rich and poor has widened, especially since 1990. From 1970 to 2017, incomes for the poorest households grew only by 12 percent, a pace similar to the regional median. During the same period, the wealthiest households saw a much larger 40 percent growth in inflation-adjusted income.

This trend is most evident in San Francisco, where households at the 60th and 80th percentile have seen incomes grow two to three times faster since 1970 than households at the 20th percentile. In 2017, household income at the 80th percentile in San Francisco exceeded $200,000, while household income at the 20th percentile remained the lowest in the region. This disparity can be attributed in part to the city’s affordable housing policy, which has made it possible for some of the lowest-income residents living in subsidized residences to stay. Meanwhile, other low- and middle-income earners without subsidized housing have moved to less expensive parts of the region or beyond.

Local Focus
The region’s highest-income households and workers continue to be concentrated in Silicon Valley.

Along with Marin County, Santa Clara and San Mateo counties have the highest household incomes among Bay Area counties. Median household incomes in these counties are above $100,000 – almost $30,000 greater than the region’s two lowest-income counties (Solano and Sonoma counties). This holds true at the city level as well. Of the five wealthiest cities in the region, only Belvedere is located outside of Silicon Valley.

Once one of the more affluent counties in the region, Contra Costa County is one of just two Bay Area counties (along with Solano County) to see inflation-adjusted incomes fall between 1970 and 2017. Contra Costa County has seen its share of low- and moderate-income households increase as housing costs in other parts of the region have grown, leading many low- and middle-income households to relocate to the county in search of lower housing costs. After accounting for inflation, the median household income in Contra Costa County today is $5,000 less than it was almost 50 years ago.

National Context
The Bay Area has the second-highest household income levels of any major metro area in the country.

Washington, D.C. is the only major metro area in the country with a higher median household income than the Bay Area. The typical Bay Area household has an income 80 percent higher than a typical household does in Miami, for example– reflecting a significant income gap between the nation’s major metro areas.

Methodology Notes: 

Total income is the sum of wage or salary income; net self-employment income; interest, dividends, or net rental or royalty income or income from estates and trusts; Social Security or Railroad Retirement income; Supplemental Security Income (SSI); public assistance or welfare payments; retirement, survivor, or disability pensions; and all other income. Receipts from the following sources are not included as income: capital gains, money received from the sale of property (unless the recipient was engaged in the business of selling such property); the value of income “in kind” from food stamps, public housing subsidies, medical care, employer contributions for individuals, etc; withdrawal of bank deposits; money borrowed; tax refunds; exchange of money between relatives living in the same household; gifts and lump-sum inheritances, insurance payments, and other type of lump-sum receipts. Income data reported in a given year reflects the income in the prior year (decennial Census) or in the prior 12 months (American Community Survey); note that this inconsistency has a minor effect on historical comparisons (for more information, go to: American Community Survey 1-year data is used for larger geographies – metropolitan areas and counties – while smaller geographies rely upon 5-year rolling average data due to their smaller sample sizes. Median income for 1970 and quintile income for 1970-2000 is imputed from Decennial Census data using methodology a developed by the California Department of Finance (for more information, go to: Bay Area income is the population weighted average of county-level income. Worker earnings is one component of household income. Worker earnings are the sum of wage or salary income and net income from self-employment. “Earnings” represent the amount of income received regularly for people 16 years old and over before deductions for personal income taxes, Social Security, bond purchases, union dues, Medicare deductions, etc. The U.S. Census has upper-limit thresholds for reporting income data. The dataset may not accurately represent median and quintile household income above the threshold. For example, in 2017 the threshold was $250,000. A city with an 80th percentile household income of $300,000 will have an 80th percentile household income of $250,001 in the dataset since $300,000 is above the upper threshold of $250,000. The threshold in reporting year dollars for each year is the following: 1970 - $25,000; 1980 - $75,000; 1990 - $150,000; 2000 - $200,000; 2005 to 2017 - $250,000. Income has been inflated using the Consumer Price Index specific to each metro area; however, some metro areas lack metro-specific CPI data back to 1970 and therefore adjusted data is unavailable for some historical data points. Note that current MSA boundaries were used for historical comparison by identifying counties included in today’s metro areas.
