A new study of Silicon Valley wealth, income and other economic measures shows vast disparities in one of the country’s wealthiest regions, with the top 10% of households holding 66% of the investable assets in the region last year.
In Santa Clara and San Mateo counties, just eight households held more wealth than the bottom 50% (nearly half a million households), according to the Silicon Valley Index, an annual report by the Silicon Valley Institute for Regional Studies, the research arm of Joint Venture Silicon Valley.
Santa Clara and San Mateo counties had 163,000 millionaire households in 2022, which the report defined as households that had more than $1 million in investable assets. That translates to less than 1% of the region’s population holding about 36% of its wealth.
And an estimated 8,300 households held more than $10 million in investable assets, according to the report.
Conversely there were about 220,000 Silicon Valley households with fewer than $5,000 in total assets.
About 23% of Silicon Valley residents lived below the poverty threshold in 2021, a 3 percentage point increase from 2019. Two percent of Silicon Valley households, or about 22,000 households, did not hold bank accounts.
