Greek-speaking Cypriots make up about 85 of the population. About 12 percent of the population is of Turkish extraction, and the remainder is made up of Armenians and other ethnic groups. Both the Greek and Turkish communities retain the customs, and, to a great extent, the national identity of their counterparts on the mainland. Since the Turkish invasion in 1974 mass migrations of Greeks and Turks have taken place, so that now the two groups are geographically separated. The Greek Cypriots occupy the southern two-thirds of the island and the Turkish Cypriots occupy the northern third. The people are predominantly farmers who work the land surrounding their villages.
