IOM Yemen DTM estimates that 1,340 migrants entered Yemen. Currently, IOM Yemen DTM does not have access to Manfath Alwadeeah FMP, on the KSA-Yemen land border point, and therefore cannot report information on Yemeni returnees. From 1st January to 30th November 2020, an estimated 35,500 migrants arrived in Yemen, and 13,895 Yemenis returned from KSA, while another 266 Yemenis returned from the Horn of Africa. The migration has witnessed a significant decline since the emergence of the Corona virus pandemic. The migrant caseload has been primarily Ethiopian (88%) and Somalis (12%), with 89% of those tracked heading for Saudi Arabia and 11% towards Yemen. The migrants are predominantly male (77%), with 14% women and 6% boys and 3% girls also among the travellers. Through the Novemebr 2020 reporting period, the highest arrivals were observed at Lahj governorate with 562 migrants entering at Al Aarah monitoring point. METHODOLOGY: DTM’s global flow monitoring methodology aims to identify areas prone to internal, cross-border and regional migration. Mobility area assessments are conducted at the national level. DTM teams then collect information at the local level to identify key transit points. Enumerators collect data from key informants at the flow monitoring points: key informants may be transport staff, custom officers, boat operators or migrants themselves. Data is collected through a basic form combined with direct observations –enabling breakdowns. LIMITATIONS: Data collected for these exercises should be understood as estimations only. They represent only part of the total flows passing through Yemen. The spatial and temporal coverage of this data collection activity is therefore incomplete. In addition, although data is collected daily, it is collected only during peak hours. The portion of the flows that occur during the uncovered hours is not represented. Data on vulnerability is based on direct observation and should be understood as mainly indicative.
