Yemen Population 2017
Yemen is one of the least developed countries in the world with the vast majority of its population in rural and tribal areas, and it's seen many conflicts and civil wars in recent history. The population is more than 5x larger than its 1950 population of 4.3 million, and Yemen has a young population as well, with almost half of its people under 15. Yemen has the 30th highest fertility rate in the world at 4.45 children per woman.
Most Yemenis are of Arab origin, as most minorities left when the former states of north and south Yemen were established. The country remains, for the most part, a tribal society with about 400 Zaydi tribes in the northern region and hereditary caste groups in urban areas, most notably Al-Akhdam.
There are 10-30,000 Turkish people still living in Yemen after their arrival with the Ottoman colonization, and there's a rather large community of Yemenite Jews. There are also large groups of Indonesians, Malaysians, and Singaporeans of Arab descent. Yemen hosts about 160,000 refugees and asylum seekers as well, mostly from Somalia, Iraq, Ethiopia and, more recently, Syria.
