Iraq Country Handbook - Europe Link

The Arab population is split between the Shi’a majority in the south and
the Sunni who live mostly in the central part of the country, around
Baghdad. There are two Arab groups that have not been assimilated into
the population. The Marsh Arabs inhabited the lower Tigris and Euphrates
River delta until this area was drained by the Iraqi government.
Most of the Marsh Arabs fled to neighboring Iran. There is also a small,
nomadic bedouin population that inhabits the desert regions.
