Unlike other people of the Arabian Peninsula who have historically been nomads or semi-nomads, Yemenis are almost entirely sedentary and live in small villages and towns scattered throughout the highlands and coastal regions.

Yemenis are divided into two principal Islamic religious groups: the Zaidi sect of the Shi'a, found in the north and northwest, and the Shafa'i school of Sunni Muslims, found in the south and southeast. Yemenis are mainly of Semitic origin, although African strains are present among inhabitants of the coastal region. Arabic is the official language, although English is increasingly understood in major cities. In the Mahra area (the extreme east), several non-Arabic languages are spoken. When the former states of north and south Yemen were established, most resident minority groups departed.
