Population density has increased along with the relatively rapid growth rate. For example, although Turkey had an average of only twenty-seven inhabitants per square kilometer in 1950, this figure had nearly tripled, to 72.5 persons people per square kilometer, by 1990. Population density was estimated at 78.5 people per square kilometer at the end of 1994. According to the 1990 census, the most densely populated provinces included Istanbul, with 1,330 persons per square kilometer Kocaeli, with 260 and Izmir, with 220. The most lightly populated provinces included Tunceli and Karaman, with seventeen and twenty-four persons, respectively, per square kilometer. Turkey's overall population density was less than one-half the densities in major EU countries such as Britain, Germany, and Italy.

Although overall population density is low, some regions of Turkey, especially Thrace and the Aegean and Black Sea coasts, are densely populated. The uneven population distribution is most obvious in the coastal area stretching from Zonguldak westward to Istanbul, then around the Sea of Marmara and south along the Aegean coast to Izmir. Although this area includes less than 25 percent of Turkey's total land, more than 45 percent of the total population lived there in 1990. In contrast, the Anatolian Plateau and mountainous east account for 62 percent of the total land, but only 40 percent of the population resided there in 1990. The remaining 15 percent of the population lived along the southern Mediterranean coast, which makes up 13 percent of Turkey's territory.

In 1990 about 50 percent of the population was classified as rural. This figure represented a decline of more than 30 percent since 1950, when the rural population accounted for 82 percent of the country's total. The rural population lived in more than 36,000 villages in 1990, most of which had fewer than 1,000 inhabitants (see Village Life, this ch.). For administrative purposes, a village can be a small settlement or a number of scattered rural households, jointly administered by a village headman (muhtar ).

By 1995 more than 65 percent of Turkey's population lived in cities, defined as built-up areas with 10,000 or more inhabitants. The urban population has been growing at a rapid rate since 1950, when it accounted for only 18 percent of Turkey's total. The main factor in the growth of the cities has been the steady migration of villagers to urban areas, a process that was continuing in the 1990s. The trend toward urbanization was revealed in the 1990 census, which enumerated more than 17.6 million people--more than 30 percent of the total population--as living in nineteen cities with populations then of more than 200,000. The largest was Istanbul, with a population then of about 6.6 million, approximately 12 percent of Turkey's overall population. Two other cities also had populations in excess of 1 million: Ankara, the capital (about 2.6 million), and Izmir, a major port and industrial center on the Aegean Sea (about 1.8 million). Turkey's fourth and fifth largest cities, 1000 , Adana (about 916,000 in 1990) and Bursa (about 835,000), have been growing at rates in excess of 3 percent per year, and each is expected to have more than 1 million inhabitants before 2000. Gaziantep in the southeast and Konya on the Anatolian Plateau were the only other cities with populations in excess of 500,000 in 1990. The ten largest cities also included Mersin (about 422,000), Kayseri (about 421,000), and Eskisehir (about 413,000).

Migration

During the decade 1915 to 1925, the country experienced large population transfers--a substantial movement outward of minority groups and an influx of refugees and immigrants. The first major population shift began in 1915, when the Ottoman government, for a variety of complex and in some instances contradictory reasons, decided to deport an estimated 2 million Armenians from their historical homeland in eastern Anatolia (see Armenians, this ch. World War I, ch. 1). The movement of Greeks out of Turkey, which began during the 1912-13 Balkan Wars, climaxed in the 1920s with an internationally sanctioned exchange of population between Turkey and the Balkan states, primarily. In accordance with the 1923 Treaty of Lausanne, Turkey accepted approximately 500,000 Muslims, who were forced to leave their homes in the Balkans, in exchange for nearly 2 million Greeks, who were forced to leave Anatolia. By special arrangement, Greeks living in Istanbul and Turks living in the Greek part of Thrace were exempted from the compulsory exchanges.

After 1925 Turkey continued to accept Muslims speaking Turkic languages as immigrants and did not discourage the emigration of members of non-Turkic minorities. More than 90 percent of all immigrants arrived from the Balkan countries. Between 1935 and 1940, for example, approximately 124,000 Bulgarians and Romanians of Turkish origin immigrated to Turkey, and between 1954 and 1956 about 35,000 Muslim Slavs immigrated from Yugoslavia. In the fifty-five-year period ending in 1980, Turkey admitted approximately 1.3 million immigrants 36 percent came from Bulgaria, 30 percent from Greece, 22.1 percent from Yugoslavia, and 8.9 percent from Romania. These Balkan immigrants, as well as smaller numbers of Turkic immigrants from Cyprus and the Soviet Union, were granted full citizenship upon their arrival in Turkey. The immigrants were settled primarily in the Marmara and Aegean regions (78 percent) and in central Anatolia (11.7 percent).

The most recent immigration influx was that of Bulgarian Turks and Bosnian Muslims. In 1989 an estimated 320,000 Bulgarian Turks fled to Turkey to escape a campaign of forced assimilation. Following the collapse of Bulgaria's communist government that same year, the number of Bulgarian Turks seeking refuge in Turkey declined to under 1,000 per month. In fact, the number of Bulgarian Turks who voluntarily repatriated--125,000--exceeded new arrivals. By March 1994, a total of 245,000 Bulgarian Turks had been granted Turkish citizenship. However, Turkey no longer regards Bulgarian Turks as refugees. Beginning in 1994, new entrants to Turkey have been detained and deported. As of December 31, 1994, an estimated 20,000 Bosnians were living in Turkey, mostly in the Istanbul area. About 2,600 were living in camps the rest were dispersed in private residences.

In 1994 the government claimed that as many as 2 million Iranians were living in Turkey, a figure that most international organizations consider to be grossly exaggerated. Turkey is one of the few countries that Iranians may enter without first obtaining a visa authorities believe that the relative ease of travel from Iran to Turkey encourages many Iranians to visit Turkey as tourists, or to use Turkey as a way station to obtain visas for the countries of Europe and North America. Consequently, as many as 2 million Iranians actually may transit Turkey--including multiple reentries for many individuals--in a given year. Specialized agencies of the European Union and the United Nations that deal with issues of migrants and refugees 84e believeve a more realistic figure of the number of Iranians who live in Turkey, and do not have a residence in Iran or elsewhere, is closer to 50,000.

In the 1960s, working-age Turks, primarily men, began migrating to Western Europe to find employment as guest workers. Many of these Turkish workers eventually brought their families to Europe. An estimated 2 million Turkish workers and their dependents resided in Western Europe in the early 1980s, before the onset of an economic recession that led to severe job losses. The Federal Republic of Germany (West Germany) initiated the program of accepting Turkish guest workers. In the 1990s, however, Germany adopted a policy of economic incentives to encourage the voluntary repatriation of Turkish workers. At the end of 1994, an estimated 1.1 million Turks continued to reside in Western Europe as semipermanent aliens. About two-thirds of these Turkish migrants lived in Germany, and another 10 percent in France. Other European countries with sizable Turkish communities included Austria, Belgium, the Netherlands, Sweden, and Switzerland. In addition, at least 150,000 Turks were working in Saudi Arabia and other Arab oil-exporting countries of the Persian Gulf.
