Definition of Ethnicity from Wikipedia:
An ethnic group is a group of human beings whose members identify with each other, usually on a presumed or real common heritage. Ethnic identity is further marked by the recognition from others of a group's distinctiveness and the recognition of common cultural, linguistic, religious, behavioral or biological traits, real or presumed, as indicators of contrast to other groups.
Definition of Ethnicity from the Journal of Law, Medicine and Ethics:
Race or ethnic identity, despite its imprecise categorization, is a useful means of identifying population differences in mechanisms of disease and treatment effects. Therefore, race and other arbitrary demographic and physiological variables have appropriately served as a helpful guide to clinical management and to clinical trial participation.
