Beersheba is the largest city in the Negev desert of Israel. It is often referred to as the "Capital of the Negev." In 2005, when the population reached 185,000, it became the sixth largest city in Israel. Beersheba is the administrative centre for the southern region of Israel and home of Ben-Gurion University of the Negev, Soroka Medical Center, and the Israel Sinfonietta Beersheba. Beersheba has grown considerably since the founding of the state in 1948. A large portion of the population is made up of Jews who immigrated to Israel from Arab countries after 1948, and newcomers from Ethiopia and the former Soviet Union. Beersheba is surrounded by a number of satellite towns: the mainly Jewish Omer, Lehavim and Metar and several Bedouin towns, the largest of which are Rahat, Tel Sheva and Lakiya.
