Israelis who live in rural areas primarily live on kibbutzim or moshavim. They settled either in established cities and towns, or in kibbutzim and moshavim. Several Hashomer Hatzair kibbutzim banded together to form Kibbutz Artzi. Members of the unit were recruited only from agricultural kibbutzim and moshavim. In 2006 there were 40 moshavim shitufi'im in Israel, compared with 267 kibbutzim. The moshavim are similar to kibbutzim with an emphasis on community labour. There are another 19 moshavim and 10 kibbutzim. Several kibbutzim, such as Kibbutz Lotan and Kfar Ruppin, operate bird-watching vacations and eco tours. Intentional communities include cohousing, residential land trusts, ecovillages, communes, kibbutzim, ashrams, and housing cooperatives. The Zionist kibbutzim and communes of the counterculture are also manifestations of utopian socialist ideas. A number of kibbutzim across Israel also offer ulpan courses. Many kibbutzim rent out homes or run guesthouses. In the 1970s kibbutzim frequently hired Arab labourers. In 1922, there were 700 people living on kibbutzim in Palestine. The urban kibbutzim are smaller and more anarchist.
