Much like the rest of the country, America's richest neighborhoods continue to evolve in terms of racial diversity.
In his latest Higley 1000, a list of the highest-income neighborhoods in the U.S., Stephen Higley, a professor emeritus of urban social geography at the University of Montevallo, found that the top neighborhoods are home to more Asian and Latino residents than ever before.
Higley ranked the most expensive neighborhoods in America based on American Community Survey 2006 - 2010 data. He aggregated contiguous block groups (subdivisions of Census tracts) with a mean income over $200,000. You can read his complete methodology here.
#25 Purchase in Harrison, N.Y.
Mean household income: $464,955
Purchase is a more rural area of the town of Harrison. It features winding roads and lots of wooded areas.
National corporations like MasterCard and PepsiCo have established their headquarters in Purchase along I-287, which is known as "Platinum Mile."
In the 1970s, some residents in Purchase pushed for the neighborhood to secede from Harrison and become its own village over concerns about overdevelopment. But the plan did not come to fruition.
Purchase is 95.1% white, 3.4% Asian, 4.9% Latino, 2.0% black
#24 Chevy Chase Village in Chevy Chase Village, Md.
Mean household income: $466,049
This village, less than a half square mile, sits on the line between Maryland and the District of Columbia. The Chevy Chase Land Company transformed the farmland into a carefully planned suburb.
The founders disdained the city aesthetic and envisioned houses with broad verandas, patterned shingles and decorative cornices.
Chevy Chase Village is 93.4% white, 1.6% Asian, 2.8% Latino, 0.5% black
#23 Everglades Club in Palm Beach, Fla.
Mean household income: $467,715
Palm Beach was established by Standard Oil Tycoon Henry Flagler in 1902 when Flagler completed construction of two luxury hotels and built himself a luxury mansion.
Within Palm Beach, the Everglades Golf Club has long been a bastion of exclusive Southern prestige and a fair bit of scandal for its membership requirements.
The club was originally built by Paris Singer, son of the sewing machine inventor, to serve as a hospital for returning World War I veterans. When the hospital failed to open, Singer turned the sprawling building into Palm Beach's first private club.
Everglades Club is 89.9% white, 0.8% Asian, 6.3% Latino, 1.4% black
