The professional class, also called the upper middle class, consists mostly of highly educated white collar salaried professionals, whose work is largely self-directed. In 2005, these household incomes commonly exceed $100,000 per year.
The PewResearch Center suggests that the middle income range is 75 percent to 150 percent of the median income. This would make the middle class income range $37,675 to $75,350. To most, this range seems small, and surveys conducted by the PewResearch Center find that many who fall outside this range still consider themselves middle class.
