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 Collectivism and Zionism. In recent decades, some kibbutzim have been privatized and changes have been made in the communal lifestyle. A member of a kibbutz is called a kibbutznik .
