In sociology, the upper middle class is the social group constituted by higher status members of the middle class. This is in contrast to the term lower middle class, which is used for the group at the opposite end of the middle-class stratum, and to the broader term middle class. There is considerable debate as to how the upper middle class might be defined. According to sociologist Max Weber, the upper middle class consists of well-educated professionals with postgraduate degrees and comfortable incomes.
The American upper middle class is defined similarly using income, education, and occupation as the predominant indicators. In the United States, the upper middle class is defined as consisting mostly of white-collar professionals who not only have above-average personal incomes and advanced educational degrees but also a higher degree of autonomy in their work. The main occupational tasks of upper middle class individuals tend to center on conceptualizing, consulting, and instruction.
