The German census only collects data on country of birth, rather than ethnicity, consequently, official figures do not provide a true representation of the total population (i.e. including German-born descendants of full or partial Turkish origin). The majority of ethnic Turks living in Germany have either arrived from or originate from Turkey; however, there are also significant ethnic Turkish communities which have come from (or descend from) other post-Ottoman nation-states in the Balkans (especially from Bulgaria and Greece), as well as from the island of Cyprus, and Lebanon. More recently, since the European migrant crisis (2014-19), there has also been a significant increase in the number of ethnic Turks from Syria, Iraq and Kosovo who have come to Germany.
