ペルシア人
According to the CIA World Factbook, Persians in Iran constitute up to 54% of the country's population. Another source, the United States Library of Congress states Iran's Persians compose 65% of the country's population. However, other sources mention that Persians only comprise 50.5%, or 55.3%. Some of these numbers include the Mazandaranis and Gilakis as Persian people, though the CIA World Factbook makes a distinction between the Persian language and the Mazandarani and Gilaki language, respectively.
