All nationals of Turkey are considered Turkish for official purposes. However, there are several hundred villages which are considered purely "Circassian", whose total "Circassian" population is estimated to be 1,000,000, although there is no official data in this respect, and the estimates are based on informal surveys. The "Circassians" in question may not always speak the languages of their ancestors, and Turkey's center-right parties, often with varying tones of Turkish nationalism, generally do well in localities where they are known to constitute sizable parts of the population (such as in Akyazı).
