United States caste system

Caste: The Origins of Our Discontents is a nonfiction book by the American journalist Isabel Wilkerson, published in August 2020 by Random House. The book describes racism in the United States as an aspect of a caste system—a society-wide system of social stratification characterized by notions such as hierarchy, inclusion and exclusion, and purity. Wilkerson does so by comparing aspects of the experience of American people of color to the caste systems of India and Nazi Germany, and she explores the impact of caste on societies shaped by them, and their people.

Facilities and services such as housing, healthcare, education, employment, and transportation have been systematically separated in the United States based on racial categorizations. Notably, racial segregation in the United States was the legally and/or socially enforced separation of African Americans from whites, as well as the separation of other ethnic minorities from majority and mainstream communities. While mainly referring to the physical separation and provision of separate facilities, it can also refer to other manifestations such as prohibitions against interracial marriage (enforced with anti-miscegenation laws), and the separation of roles within an institution. The U.S. Armed Forces were formally segregated until 1948, as black units were separated from white units but were still typically led by white officers.
