IOM Yemen DTM’s Flow Monitoring Registry (FMR) monitors migrant arrival on the southern coastal border and Yemeni return locations on Yemen's northern border with the Kingdom of Saudi Arabia (KSA). Enumerators placed at Flow Monitoring Points (FMPs) record arrivals of migrants and returning Yemeni nationals in order to identify different patterns of migration, and to provide quantitative estimates to help define the population of irregular migrants entering the country. FMR is not representative of all flows in Yemen and should be understood as only indicative of the individuals recorded at FMPs during the time frame indicated. Access constraints limit the ability to collect data at some migrant arrival points. In September 2021, IOM Yemen DTM estimates that 2,769 migrants entered Yemen, compared to 1,756 migrants in August 2021. The increase in the number of migrants in September comparing to August is due to improved weather conditions allowing boats to travel to landing points on Yemen’s coastal side. TM estimates that 4,228 Yemeni returns from KSA during the month of September 2021, compared to 2,769 in August and 1,821 Yemenis in July 2021. During the period between 1 January and 30 September 2021, an estimated 16,080 migrants and 10,050 Yemenis arrived in Yemen.
