There is a need for more data on remittances in forced displacement situations to help policy makers maximize the positive impacts of remittances and minimize their risks. There are, however, a number of methodological challenges with surveys on remittances in general, and even more so in the forced displacement context. The brief aims to raise awareness of these specific challenges and propose potential solutions when using existing longitudinal multi-purpose household surveys or conducting a survey specific to remittances in the context of forced displacement. Focus is on surveys with refugees and IDPs themselves but surveys with households that send remittances to them or receive remittances from them can also provide important information.
