7 Wealthiest California Counties

The United States, despite a somewhat unpredictable economy, housing market and inflation rate, is a country of incredible wealth.

Indeed, there are concentrations of extraordinarily high wealth throughout America, with certain counties serving as home for some of the richest people on Earth. While the state of Virginia has the highest concentration of moneyed counties in the country (nine of the 50 richest counties are located there), it likely comes as no surprise that California has the single wealthiest county of all.

San Mateo County has an average household income over $200,000, and the typical home costs nearly $2 million. California has a number of other quite moneyed counties as well.

Using the 2022 American Community Survey and sourcing home values from Zillow, GOBankingRates compiled a list of the seven wealthiest counties in California.
