The Hausa are the largest ethnic group, forming 56% of the total population. The Djerma-Songhai, the second-largest group, constitute 22% of the population. They, like the Hausa, are sedentary farmers living on the arable southern tier. The Djerma-Songhai are concentrated in the southwest; the Hausa, in south-central and southeast Niger. Many of Niger's inhabitants are nomadic or seminomadic livestock-raising peoples, including the Fulani, or Peul (8.5%), the Tuareg (8%), and the Beri Beri or Kanouri (4.3%). Arab, Toubou, and Gourmantche peoples make up the remaining 1.2% of the populace, along with some 1,200 French expatriates.
