Just looked into Arizona's wealthiest neighborhoods and honestly, the wealth concentration is wild. Most of the money clusters around two areas — the Phoenix-Mesa-Chandler metro and Tucson. The Phoenix side absolutely dominates with 14 of the top 20 richest suburbs, while Tucson takes the remaining 6. What's interesting is how diverse the income levels are even within the wealthy tier. You've got Surprise near Phoenix pulling in around $107k average household income, but jump to the top and Catalina Foothills in Tucson hits $170k+. The home values tell a similar story — cheaper options in the $360-430k range, but premium Mesa Phoenix area suburbs like Scottsdale and Fountain Hills pushing past $750k easily. Scottsdale's the second richest with $168k average income and nearly $940k typical home values. If you're looking at Arizona real estate, the Phoenix-Mesa corridor clearly has the most affluent suburbs concentrated there, though Tucson's top picks like Catalina Foothills compete surprisingly well. Data's based on 2023 census info with 2025 home valuations, so pretty current snapshot of where Arizona's wealth actually sits.
