American middle class

Though the American middle class does not have a definitive definition,^[1] contemporary social scientists have put forward several ostensibly congruent theories on it. Depending on the class model used, the middle class constitutes anywhere from 25% to 75% of households.

One of the first major studies of the middle class in America was White Collar: The American Middle Classes, published in 1951 by sociologist C. Wright Mills. Later sociologists such as Dennis Gilbert commonly divide the middle class into two sub-groups: the professional or upper middle class (~15-20% of all households) consisting of highly educated, salaried professionals and managers, and the lower middle class (~33% of all households) consisting mostly of semi-professionals, skilled craftsmen and lower-level management.^[2][3] Middle-class persons commonly have a comfortable standard of living, significant economic security, considerable work autonomy and rely on their expertise to sustain themselves.^[4]

Members of the middle class belong to diverse groups which overlap with each other. Overall, middle-class persons, especially upper-middle-class individuals, are characterized by conceptualizing, creating and consulting. Thus, college education is one of the main indicators of middle-class status. Largely attributed to the nature of middle-class occupations, middle class values tend to emphasize independence, adherence to intrinsic standards, valuing innovation and respecting non-conformity.^[2][4] The middle class is more politically active than other demographics.^[5] The middle classes are very influential as they encompass the majority of voters, writers, teachers, journalists and editors.^[6] Most societal trends in the U.S. originate within the middle classes.^[7]

According to a 2021 Pew Research study that classifies adults as middle class if they belong to a household with income between 2/3 and 2x median household income ($52k-$156k for a household of three), the percentage of Americans in the middle class declined from 61% to 50% over the previous five decades (1971-2021) with 4% moving down into the lower class and 7% moving up into the upper class.^[8] In 2019, as defined by the Future of the Middle Class Initiative to be the middle 60 percent of the income distribution, and looking only at individuals 25-54: 59 percent were white, 18 percent Hispanic, 12 percent Black, and 10 percent “other.”^[9]
