Just looked at the latest data on America's wealthiest suburbs and some interesting patterns are emerging. Scarsdale, New York is still holding the top spot for the second year running with an average household income around 601k, but what caught my eye is how much California is dominating the rankings now. They've got 17 of the top 50 richest zip codes in the country, up from 16 last year.

What's wild is seeing which suburbs are making a sudden jump. Alamo and Southlake both cracked the top 10 this year, with Southlake jumping from 13th place. California suburbs like Los Altos and Alamo are pushing close to 403k in average household income, though interestingly their home values are way higher than the income would suggest - we're talking 2.5 to 4.5 million for homes in some of these neighborhoods. Texas is also punching above its weight with five suburbs in the top 50, including three in the top 10.

The home value appreciation is interesting too. Places like Los Altos saw a 6.1% jump year-over-year, while some California suburbs actually dipped slightly. Meanwhile, Dix Hills in New York had a wild 13.3% increase in home values. If you're looking at the highest-income neighborhoods across America, you're basically looking at a California and Texas story right now, with a few spots in the Northeast still holding their ground. The data suggests the wealth is concentrating in these specific zip codes more than ever.
