khuzestan, unlike most other provinces in Iran, is inhabited by a number of ethnic minorities and peoples: Persians in major cities, Iranian Arabs, Lurs, Mizrahi Jews, Laks of the north, the Turkic-speaking Qashqai and Afshari tribes, the Khuzis of Shush (Susa), Dezful, Shushtar, Andimeshk and the inhabitants of the coastal regions of the Persian Gulf all make up the population of the province of khuzestan.
Many Khuzestanis are bilingual, speaking both Persian and Arabic. The Arabic spoken in khuzestan is Mesopotamian Arabic, the same Dialect as is spoken in Iraq.
The Persian and Lurish groups of western khuzestan all speak distinct dialects unique to their areas. Shushtari, Dezfuli and Behbahani are other dialects spoken in khuzestan.
It is also not uncommon to find people able to speak a variety of indigenous dialects in addition to their own.
