Middle class is a range, not a fixed salary
In the U.S., middle-class income is best understood as a range tied to local living costs and household composition. A salary that supports a middle-class standard in one metro may feel stretched in another with higher housing and childcare burdens. Because of this, national figures are useful reference points but weak decision tools on their own.
A practical definition focuses on outcomes: stable housing, routine savings, manageable debt, and the ability to absorb moderate financial shocks without immediate crisis.
