The kibbutz is a self-contained social and economic unit where property and means of production are communally owned. Members work in different branches of the kibbutz economy. Traditionally the backbone of Israel's agriculture, kibbutzim are now increasingly engaged in industry, tourism, and services. Many kibbutzim have modified their traditional collective approach and are in various stages of privatization. Dganya, established in 1909 on the shores of the Sea of Galilee, was the original kibbutz. By 1948, 6.5% of the entire Israeli population lived in a kibbutz. Today 1.7% of the population lives in 267 kibbutzim, each comprised of between 100-1000 members.
