The 14 Richest Counties In America Might Make You Pause

It's common to compare wealth between different countries and even states within America, but how does this financial metric look on the county level? 

Money Digest pulled together the 14 richest counties in the United States to highlight where some of the strongest local economies and highest earners are located. We looked at median household income data from the U.S. Census Bureau's 2025 American Community Survey 1-year estimates, which provide the latest full-year data for counties with at least 65,000 residents. Digging a little deeper, the percentage of households earning over $200,000 offers further context. To account for potential inequality, poverty rates were included, too.

Since income only tells one part of the story, we also looked at median home values and mortgage costs as a percentage of annual earnings. Additionally, the wealthiest counties in America share some overlapping economic reasons for their higher position on the earning ladder. Whether you're considering a move to one of these top-earning localities or simply wonder where the country's wealth is concentrated, these extraordinary figures might make you pause. 

Loudoun County, Virginia tops the list of the richest counties in the U.S. with a median household income of $193,191. For reference, that's about 127.87% above the national median household income of $84,780. Notably, 48.72% of households in this county earn more than $200,000. The poverty rate in Loudoun County is 3.4%, compared to the national average of around 10%.

Meanwhile, the county's median home value is $819,200. Unsurprisingly, housing costs are one of the reasons retirees regret moving to Virginia – the state with the highest representation among the richest counties in the country. According to a Congressional Research Service report, households spending more than 30% of their income on housing are considered "cost-burdened." In Loudoun County, about 23.2% of mortgaged homeowners fall under this rubric, while 7.5% spend half or more of their income on housing costs.

According to Loudoun County Economic Development, more than 60% of people living in the area have a bachelor's degree or higher.

The county's proximity to Washington, D.C. further explains the wealth concentration.

In Santa Clara County, California, the median household income stands at $169,499, which is 99.93% above the baseline in the U.S. This positioning makes sense given that California is one of the states where some of the wealthiest people in America live.
