Tel Aviv is the second most populous city and the largest metropolitan area in Israel. It has a population of 410,000 and a land area of 52 km2 (20 sq mi). The city is located on the Israeli Mediterranean coastline in central-west Israel, in Gush Dan, Israel's largest metropolitan area, containing 42% of Israel's population. It is also the largest and most populous city in Gush Dan, which is collectively home to 3,405,000 residents] The city is governed by the Tel Aviv-Yafo municipality, headed by Ron Huldai. Residents of Tel Aviv are referred to as Tel Avivim (singular: Tel Avivi). As the United Nations and most countries do not recognize Jerusalem as the capital of Israel, Tel Aviv is home to many foreign embassies.
Tel Aviv was founded by the Jewish community on the outskirts of the ancient port city of Jaffa in 1909. Jewish immigration meant that the growth of Tel Aviv soon outpaced Jaffa, which had a majority Arab population at the time. Tel Aviv and Jaffa were merged into a single municipality in 1950, two years after the establishment of the State of Israel. Tel Aviv's White City, designated a UNESCO World Heritage Site in 2003, comprises the world's largest concentration of Bauhaus buildings.
Tel Aviv is an economic hub, home to the Tel Aviv Stock Exchange, corporate offices and research and development centers. It is the country's financial capital and a major performing arts and business center. Tel Aviv has the second-largest economy in the Middle East after Dubai, and is the 31st most expensive city in the world. With 2.5 million international visitors annually, Tel Aviv is the fifth-most-visited city in the Middle East and Africa. It is known as "the city that never sleeps" and a "party capital" due to its thriving nightlife, young atmosphere and famous 24-hour culture.
