Tel Aviv has the third- or fourth-largest economy and the largest economy per capita in the Middle East. The city has the 31st highest cost of living in the world. Tel Aviv receives over 2.5 million international visitors annually. A "party capital" in the Middle East, it has a lively nightlife and 24-hour culture.
The city was founded in 1909 by the Yishuv (Jewish residents) as a modern housing estate on the outskirts of the ancient port city of Jaffa (Hebrew: ????? Yafo), then part of the Jerusalem province of Ottoman Syria.
'Tel Aviv'. means "Ancient Hill of Spring". Other Jewish suburbs of Jaffa established outside Jaffa's Old City even before Tel Aviv, eventually became part of Tel Aviv, the oldest among them being Neve Tzedek (est. 1886).
Immigration by mostly Jewish refugees meant that the growth of Tel Aviv soon outpaced that of Jaffa, which had a majority Arab population at the time. Tel Aviv and Jaffa were later merged into a single municipality in 1950, two years after the Israeli Declaration of Independence, which was proclaimed in the city. Tel Aviv's White City, designated a UNESCO World Heritage Site in 2003, comprises the world's largest concentration of International Style buildings, including Bauhaus and other related modernist architectural styles.
