Demographics
Elton Daniel in The History of Iran (Greenwood Press, 2001), states that the Arabs of Iran "are concentrated in the province of Khuzistan and number about half a million". The Historical Dictionary of Iran puts the number at 1 million.
According to the Encyclopædia Britannica, "More than half the population are Arabs who live in the plains; the rest are Bakhtyaris and other Lurs (peoples of West Persia), with many Persians in the cities. Some of the Bakhtyaris and Lurs are still nomads."
