Usage notes
In common use, ethnicity is used as a euphemism for the sensitive term race, but with identical meaning: group ancestry and physical characteristics, such as skin color, as in “ethnic Chinese”. In careful use, it refers to any common characteristic or identity, particularly linguistic, national, regional, or religious groups, and can cut across race, such as Hispanic/Latino; or be a subgroup of a racial group, as in German Texan, Chinese Indonesians, Nuyorican (New York Puerto Rican), etc.
