Around 30,000 refugees have been relocated by the Bangladesh government to Bhasan Char, and further plans exist to relocate about 100,000 refugees. To assess the conditions relocated refugees live under and that future relocations could be subject to, the Cox's Bazar Panel Survey was extended to cover Bhasan Char. The panel survey was jointly led by Gender & Adolescence: Global Evidence programme from ODI, UK, the Poverty & Equity Global Practice of the World Bank, and the Yale Research Initiative on Innovation and Scale (Y-RISE) at Yale University. Some questions were rephrased or added to fit the island context and did not cover host communities as no Bangladeshi nationals other than support staff live on the island. The survey was implemented in late-2022 and covered 962 households and 4,484 individuals.
