A kibbutz (Hebrew: קיבוץ, קִבּוּץ, lit. "gathering, clustering"; plural kibbutzim) is a collective community in Israel that was traditionally based on agriculture. Today, farming has been partly supplanted by other economic branches, including industrial plants and high-tech enterprises. Kibbutzim began as utopian communities, a combination of socialism and Zionism. Over the last decades, most Kibbutzim have been privatized and no longer practice communal living. Less than five percent of Israelis live on kibbutzim. A member of a Kibbutz is called a Kibbutznik (Hebrew: קִבּוּצְנִיק‎).
