Socotra Archipelago, Republic Of Yemen, Indian Ocean

The majority of male residents on Socotra are reported to be in the J' subclade of Y-DNA haplogroup J. Several of the female lineages on the island, notably those in mtDNA haplogroup N, are found nowhere else on earth.
Almost all inhabitants of Socotra, numbering nearly 50,000, live on the homonymous main island of the archipelago. The principal city, Hadibu (with a population of 8,545 at the census of 2004); the second largest town, Qulansiyah (population 3,862); and Qād̨ub (population 929) are all located on the north coast of the island of Socotra. Only about 450 people live on 'Abd-al-Kūrī and 100 on Samha; the island of Darsa and the islets of the archipelago are uninhabited.
The archipelago forms two districts of the Hadhramaut Governorate:
- the district of Hadibu (حديبو), with a population of 32,285 and a district seat at Hadibu, consists of the eastern two-thirds of the main island of Socotra;
