But who really is middle-class? The Washington Post created a calculator to help you figure that out. If you enter your household income and county, the calculator tells you whether you fall below, in or above the middle class in your county and of households nationally, "using the average U.S. household size (2.5 people)."
Where you live matters, the Post notes, since median income varies drastically by location. In some cities, having a small family and a $150,000 salary would put you way above the middle class. In others, you'd still be considered middle of the pack.
Below, CNBC Make It highlighted eight U.S. cities where a sizable $150,000 annual salary puts you in the middle class, not above it, and what you have to earn to qualify as upper-class.
Cities are listed in ascending order of salary required to be considered upper-class. Note that these are a selection and not the only cities where $150,000 puts you in the middle.
