The various ethnolinguistic groups found in the Caucasus, Central Asia, Europe, the Middle East, North Africa and/or South Asia demonstrate differing rates of particular Y-DNA haplogroups.
In the table below, the first two columns identify ethnolinguistic groups. Subsequent columns represent the sample size (n) of the study or studies cited, and the percentage of each haplogroup found in that particular sample.
Ethnic nationalism, also known as ethnonationalism, is a form of nationalism wherein the nation and nationality are defined in terms of ethnicity, with emphasis on an ethnocentric (and in some cases an ethnostate/ethnocratic) approach to various political issues related to national affirmation of a particular ethnic group.
The central tenet of ethnic nationalists is that "nations are defined by a shared heritage, which usually includes a common language, a common faith, and a common ethnic ancestry". Those of other ethnicities may be classified as second-class citizens. Because of these attributes, ethnic nationalism is closely related to nativism, and is associated with the radical right.
