1. Race, people, ethnicity, ethnic group, and nation are terms for a large body of persons who may be thought of as a unit because of common characteristics. Race is no longer in technical use as a biological or anthropological system of classification (see usage note). In certain broader or less technical senses, race is sometimes used interchangeably with people. People refers to a body of persons united usually by common interests, ideals, or culture but sometimes also by a common history, or language: We are one people; the peoples of the world; the Swedish people. As with people, members of an ethnicity or ethnic group are united by a shared culture or culture of origin and sometimes shared history, language, or religion, especially in contrast to the culture of a different group: Several ethnicities were represented in the Pride parade. Hostility between ethnic groups divided the region. Nation refers to a current or historical body of persons living under an organized government or rule, occupying a defined area, and acting as a unit in matters of peace and war: the English nation; the Phoenician nation.
