With median home prices consistently rising, the list of the richest counties in the U.S. only keeps getting longer. And while you might think the wealthiest places are only by the coast, you’ll be surprised to find out that’s not exactly the case. If we had to describe them by a single characteristic, there’s one thing that the top richest counties in the U.S. have in common—they have a small population. 

These Are The Wealthiest Counties in the U.S.

Located in the northwestern part of the San Francisco Bay Area, Marin County had the sixth highest income per capita of all U.S. counties in 2019.

1. Marin County, California

Median home price: $1,480,900

Not all counties are created equal; some are just affluent by nature. Marin County might be the smallest in the Bay Area, but what it lacks in size, it makes up with scenic views and a comfortable lifestyle. The county’s mild weather, proximity to San Francisco, and top-notch education make it one of the most sought-after in the U.S. 

2. San Mateo County, California

Median home price: $1,645,480

Vast open spaces and flourishing agriculture make San Mateo County superior to surrounding counties. Bordered by the Pacific Ocean to the west and San Francisco Bay to the east, this county is one of the best places in California for finding jobs. Residents of San Mateo are affiliated with the bioscience, computer software, and green technology industries, making it one of the wealthiest counties in the U.S

Loudoun County has been ranked first in the United States in median household income since 2008.

3. Loudoun County, Virginia

Virginia’s Loudoun County is one of the fastest-growing in America.

Crime rates are the lowest in the state as well, attracting families from all over the country.  

4. Los Alamos County, New Mexico

Median home price: $359,500

A small county with a big reputation, Los Alamos has faced unprecedented growth in the past few years. The area is known for its scientific and technological development as well as its excellent educational system; it's only fair that it’s considered one of the wealthiest counties in America. In terms of quality of life, Los Alamos County raises the standard of living— child poverty rates here are the lowest in the entire country. 

5. Santa Clara County, California

Median home price: $1,481,010

Is it even possible to have a list of the most expensive counties in the U.S. without mentioning Silicon Valley? Santa Clara County is home to San Jose, the largest city in Northern California by both population and area. With high-quality amenities and a bustling tech hub, Santa Clara County houses many of the Golden State's most expensive cities

Orange County is a tourist center since it's home to attractions like Disneyland, Knott's Berry Farm, and Mission San Juan Capistrano.

6. Orange County, California

Median home price: $935, 200

Anyone who’s seen The O.C. knows that Orange County is one of the most expensive in the US.

With several luxurious cities to move to, the O.C. is a destination you’d love to call home.

7. Nassau County, New York

Median home price: $666,940

Nassau County is where you’ll find many of the country's expensive cities. But don’t fret; it’s also one of the highest-income counties in the U.S. The beautiful suburban neighborhoods call for a relaxed lifestyle, away from the hustle and bustle of the surrounding cities. The county is in close proximity to New York City, and the easy commute allows you to enjoy the best of both worlds.  

As the seventh most populous county in California, Alameda is part of the San Francisco–Oakland–Berkeley metro area.

8. Alameda County, California

Median home price: $1,129,790

Alameda County has seen a surge in its population recently, all thanks to the tight-knit community, abundance of activities, and exceptional public schools. This has also increased the diversity rates of the area. You might end up moving here for education, but you’ll certainly want to stay in one of the richest counties in the U.S. long-term.  

9. Placer County, California

Median home price: $673,870

A great place to live, work, study, and play, Placer County is where living is bliss.

A coastal lifestyle that’s not as pricey as L.A. (but close enough to make a day trip out of it) might just be the answer to your question.
