Demographics

The period after the 1960s and the 1970s saw another blow to the fabric of İzmir, when local administrations tended to neglect İzmir's traditional values and landmarks. For many inhabitants, this was as serious as the 1922 fire. Some administrators were not always in tune with the central government in Ankara and regularly fell short of government subsidies, and the city absorbed huge waves of immigration from inland Anatolia, causing a population explosion. Today, it is not surprising that many inhabitants of İzmir (similar to residents of other prominent Turkish cities) look back with nostalgia to a cozier, more manageable city, which came to an end in the last few decades.

The Floor Ownership Law of 1965 (Kat Mülkiyeti Kanunu), allowing and encouraging arrangements between house or land proprietors and building contractors by which each would share the benefits of renting out eight-floor apartment blocks built to replace former single-family houses, proved especially disastrous for the urban landscape.

Modern İzmir is growing in several directions at the same time. The north-western corridor extending to Aliağa brings together both mass housing projects, including villa-type projects and intensive industrial area, including an oil refinery. In the southern corridor towards Gaziemir yet another important growth trend is observed, contributed to by the Aegean Free Zone, light industry, the airport and mass housing projects. The presence of the Tahtalı Dam, built to provide drinking water, and its protected zone did not check urban spread here, which has offshoots in cooperatives outside the metropolitan area as far south as the Ayrancılar– Torbalı axis.

To the east and the north-east, urban development ends near the natural barriers constituted respectively by the Belkahve (Mount Nif) and Sabuncubeli (Mount Yamanlar - Mount Sipylus) passes. But the settlements both above Bornova, inside the metropolitan zone, and around Kemalpaşa and Ulucak, outside the metropolitan zone, see mass housing and secondary residences development.

More recently, the metropolitan area displays growth, especially along the western corridor, encouraged by the Çeşme motorway and extending to districts outside the city of İzmir proper, such as Seferihisar and Urla. The population of the city is predominantly Muslim, but it was predominantly non-Muslim up to the earlier quarter of the 20th century.

İzmir is also home to Turkey's second largest Jewish community after Istanbul, numbering about 2,500. The community is still concentrated in their traditional quarter of Karataş. Smyrniot Jews like Sabbatai Zevi and Darío Moreno were among famous figures in the city's Jewish community. Others include the Pallache family with three grand rabbis: Haim, Abraham, and Nissim.

The Catholic Levantines of İzmir, who are mostly of Genoese and to a lesser degree of French and Venetian descent, live mainly in the districts of Bornova and Buca. One of the most prominent present-day figures of the community is Caroline Giraud Koç, wife of the renowned Turkish industrialist Mustafa Koç, whose company, Koç Holding, is one of the largest family-owned industrial conglomerates in the world.

İzmir once had a large Greek and Armenian community, but after the great fire of 1922 and the end of the Greco-Turkish War, many of the Greeks remaining in the city fled, were killed or forced to leave under the terms of the 1923 population exchange between Greece and Turkey.

Turkey is home to tens of thousands of black citizens descended from the African slave trade in the Ottoman Empire that can be traced back to the 14th century. Known as Afro-Turks, İzmir and the surrounding areas on the Aegean coast is a central hub for this population.
