POC

person(s) of color; people of color

Being a POC in Vermont has been lonely for me and the other Vermonters of color I've met. We've lived most our lives as the only ones; the only POC in our classes, the only POC in our extracurricular activities, the only POC (excluding family members) in our neighborhoods.

… many of our artists are POCs that felt excluded from Vancouver's electronic music scene, so we carved our own space.

… donate proceeds to the many POC doing revolutionary work at various levels of the industry.

A theory of classism
In a 2012 paper in Psychological Review, Kraus, Piff, University of California, Berkeley, psychology professor Dacher Keltner, PhD, and colleagues posit that social class — which they define as "a social context that individuals inhabit in enduring and pervasive ways over time" — is a fundamental lens through which we see ourselves and others. Because lower ranking people have fewer resources and opportunities than those of relatively high rank, they tend to believe that external, uncontrollable social forces and others' power have correspondingly greater influence over their lives. Success for them, therefore, depends on how well they can "read," rely on and help out others, the psychologists' theory holds.
By contrast, those who enjoy more resources and greater class status live in contexts that enhance their personal power and freedom — larger and safer living spaces, the means to buy high-priced goods and experiences, and education that provides access to influential people, ideas and venues. These conditions give rise to a more self-focused approach to life, the theory states.

"With wealth and privilege comes this island of sorts, this increased insularity from others," as Piff puts it. 
Another important aspect of the theory is that rank is, in part, subjective and relative. All relationships are marked by class scrutiny: Am I higher or lower than this person? Research also shows that people tend to be quite accurate in their assessment of their own and others' class rank, and that this self-assessment likewise predicts outcomes. For example, people who perceive themselves as lower in rank have worse health outcomes overall than those who see themselves as higher ranking, research finds.

social class, also called class, a group of people within a society who possess the same socioeconomic status. Besides being important in social theory, the concept of class as a collection of individuals sharing similar economic circumstances has been widely used in censuses and in studies of social mobility.

History and usage of the term

The term class first came into wide use in the early 19th century, replacing such terms as rank and order as descriptions of the major hierarchical groupings in society. This usage reflected changes in the structure of western European societies after the industrial and political revolutions of the late 18th century. Feudal distinctions of rank were declining in importance, and the new social groups that were developing—the commercial and industrial capitalists and the urban working class in the new factories—were defined mainly in economic terms, either by the ownership of capital or, conversely, by dependence on wages. Although the term class has been applied to social groups in a wide range of societies, including ancient city-states, early empires, and caste or feudal societies, it is most usefully confined to the social divisions in modern societies, particularly industrialized ones. Social classes must be distinguished from status groups; the former are based primarily upon economic interests, while the latter are constituted by evaluations of the honour or prestige of an occupation, cultural position, or family descent.
