Yemeni diaspora refers to Yemeni migrants and their descendants who, whether by choice or coercion, emigrated from Yemen and now reside in other countries. There are 7 million Yemenis living outside Yemen, including 2 million in Saudi Arabia. In the United Kingdom there are between 70,000 and 80,000 Yemenis. An estimated 10,000 Yemenis in Birmingham, making about 1% of the city's population. Over 200,000 Yemenis reside in the United States, and around 3,000 live in Italy. Other Yemenis also reside in the United Arab Emirates, Jordan, Qatar, Bahrain and Turkey—as well as Indonesia, Malaysia, Brunei, and the former USSR. Yemeni merchants and sailors often from the Hadhramaut and Aden regions, due to their historical maritime trading networks, were often influential in spreading Islam to regions in the Indian Ocean, especially the Swahili Coast, Madagascar, Southern India, Sri Lanka, East Timor, Indonesia, and Malaysia. A smaller number of modern-day Indonesians are of Yemeni descent, their original ancestors having left Yemen for the Southeast Asia over four centuries ago; Yemenis also contribute part of the small Muslim community in East Timor. Similarly, many South Indian and Malagasy Muslims trace their ancestry back to Yemeni migrants, contributing to the Yemeni Indian population of roughly 300,000, as well as a population of roughly 60,000 Yemenis in Madagascar. Due to the conflict in Yemen, many have migrated to the northern coasts of Djibouti, Somalia and Ethiopia. In 2017, Djibouti was home to over 40,000 Yemeni refugees. Some Yemenis also migrated to Turkey following the Yemeni Civil War since 2014. There were reports about Yemenis had been affected by/victims of the brutal 2023 Turkey-Syria earthquake in Turkey, both of them were identified as diaspora before/refugees following the 2014 Yemeni Civil War outbreak.
