There were many affected populations who could be grouped by various (often overlapping) variables such as geographic, ethnic, religious, political, and health categories. They included German political prisoners of the SA, Gestapo, and SS; foreign civilian men and women from occupied territories of Eastern Europe (Ostarbeiter); prisoners of war; institutionalized people (mentally or physically disabled people, or medical and psychiatric patients); and various ethnic, religious, or ethnoreligious groupings (for example, Jews, Sinti, Romani, Yeniche, and Jehovah's Witnesses). They lived in various kinds of camps, called labor camps (Arbeitslager in German) and concentration camps (Konzentrationslager [KZ] in German).
