Greek and Turkish Cypriots share many customs but maintain separate ethnic identities based on religion, language, and close ties with their respective motherlands. Greeks comprise 77% of the island's population, Turks 18%, while the remaining 5% are of other ethnicities.

After the Turkish invasion of 1974, about 150.000 Turks from Anatolia were transferred or decided to settle in the north. This number also includes many Kurds. This has changed the actual demographic structure of the island. In the years since the census data was gathered in 2000, Cyprus has also seen a large influx of guest workers from countries such as Thailand, the Philippines and Sri Lanka, as well as major increases in the numbers of permanent British residents. Since the country joined the European Union, a significant Polish population has also grown up, joining sizeable communities from Russia and Ukraine (mostly Pontic Greeks, immigrating after the fall of the Eastern Bloc), Bulgaria, Romania and Eastern European states.
