Tel Aviv–Yafo or Tel Aviv–Jaffa (Hebrew: Tel Aviv–Yafo; Arabic: Tall ʾAbīb - Yāfā), often referred to as just Tel Aviv, is the most populous city in the largest metropolitan area of Israel.
Located on the country's Mediterranean coastline and with a population of 443,939, it is the economic and technological center of the country.
If East Jerusalem is considered part of Israel, Tel Aviv is the country's second most populous city after Jerusalem; if not, Tel Aviv is the most populous city before West Jerusalem.
Tel Aviv is governed by the Tel Aviv-Yafo Municipality, headed by Mayor Ron Huldai, and is home to many foreign embassies. It is a global city and is ranked 25th in the Global Financial Centres Index.
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. Tel Aviv is home to Tel Aviv University, the largest university in the country with more than 30,000 students.
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, then part of the Jerusalem province of Ottoman Syria.
It was at first called 'Ahuzat Bayit' (lit. "House Estate" or "Homestead"), the name of the association which established the neighbourhood, a name changed the following year to 'Tel Aviv'.
Its name means "Tell of Spring", symbolising both ancient legacy and renewal. 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.
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.
