The National Strategy on Myanmar Refugees and Undocumented Myanmar Nationals (UMN) formulated by the Government of Bangladesh highlights the fact that more than 300,000 Rohingyasl have crossed the border and are living in Bangladesh. Following an outbreak of violence on 9 October 2016 in the Rakhine State of Myanmar, approximately more than 80,000 UMNs fled to Bangladesh. The influx slowed in late February 2017, however more new arrivals from Myanmar were reported in the month of July. The majority of UMNs are living in Ukhia and Teknaf upazilas of Cox's Bazar district, a district bordering Myanmar identified as the main entry area for border crossing.
A total of 57 sites were assessed. 164,000 UMNs were identified in 2 upazilas of Cox's Bazar district. An additional 4 sites, with a population of 635 according to NPM Round 2 (April 2017) were not assessed in this round due to limited access. Among those assessed, 52% are women and girls. 87,000 arrived since Oct 2016, with an increase in both makeshift settlements and host communities, due to newly arrived UMNs across the border from Myanmar in the month of July.
