Ethnicity
While a categorization of a "Persian" ethnic group persists in the West, Persians have generally been a pan-national group often comprising regional people who often refer to themselves as 'Persians' and have also often used the term "Iranian" (in the ethnic-cultural sense). As a pan-national group, defining Persians as an ethnic group, at least in terms used in the West, is not inclusive since the ethnonym "Persian" includes several Iranian people including the speakers of Modern Persian. Some scholars, classify the speakers of Persian language as a single ethnic unit (the ‘Persians’) and exclude those Iranians who speak dialects of Persian, or other Iranian dialects closely related to Persian; however this approach to ethnicity in Iran is erroneous, since the designation Iranian (Irani) as an ethnic term has been used by all these ethnic group in Iran, including the "Persians" irrespective of their origin, language and religion.
