See American Professional/Managerial middle class for a complete overview of the American middle classes.

The upper middle class in the United States is a sociological concept referring to the social group constituted by higher-status members of the middle class. This is in contrast to the term lower middle class, which refers to the group at the opposite end of the middle class scale. There is considerable debate as to how the upper middle class might be defined. According to Max Weber, the upper middle class consists of well-educated professionals with graduate degrees and comfortable incomes.
