Just looked at the latest data on America's richest counties and wealthiest neighborhoods, and there's some interesting stuff happening. Scarsdale, New York is still sitting at the top for the second year running with an average household income around 601k, but what really caught my attention is how much California is dominating the rankings. They've got 17 of the top 50 wealthiest areas now, up from 16 last year. Los Altos is showing some serious real estate appreciation too at over 4.5 million average home value.

Texas is making a real move though. Five suburbs in the top 50 with three in the top 10 including West University Place in Houston at number 3. Southlake jumped from 13th to 7th this year which is pretty wild. Meanwhile some of these California suburbs like Alamo and Orinda are seeing home values actually dip slightly even though household incomes are still strong.

What surprised me most was how the richest counties in the United States are spreading out geographically. It's not just the usual coastal hotspots anymore. You've got Mountain Brook, Alabama showing up with almost 10% income growth year over year, and places like Brentwood, Tennessee entering the top 50. The most expensive neighborhoods are still concentrated around San Francisco and Los Angeles, but the wealthiest areas by household income are much more diverse.

Palm Beach, Florida at number 13 has the wildest home values though at over 10 million average. That's the kind of extreme wealth that skews everything. If you're looking at where the richest neighborhoods in the country actually are by income metrics rather than just price tags, the data's pretty interesting. California suburbs still dominate but Texas and some East Coast areas are catching up fast.
