"Middle class income requirements vary across US states"

Consumer finance site SmartAsset analyzed the high and low-end of middle-class salaries in 100 large cities and every state using 2021 U.S. Census Bureau data, adopting what the Pew Research Center defines as "middle class" (Americans whose income ranges from two-thirds to two times the median household income.) In Arizona, Gilbert has the highest median household income of $104,802, and a middle-class income ranges from $70,217 to $209,604, while Tucson ranks 89th, with a middle-class income range from $33,705 to $100,612. Nationwide, a national salary range for a three-person household was around $52,000 to $156,000.
