Chapter 1 In terms of returns, some 667,400 refugees returned to their countries of origin in 2017 compared with 552,000 in 2016. Still, these returns continued to represent only a small fraction of the refugee population (3 per cent). The majority of refugees returned to Nigeria, the Central African Republic, Syria, and Afghanistan. Around 4.2 million IDPs returned, accounting for 11 per cent of the overall IDP population. UNHCR has voiced concern about the voluntariness of some of these returns as well as the conditions into which displaced people are returning.12 In some cases, refugees and IDPs 8 are returning under adverse circumstances in which conditions for safe and sustainable returns are not yet in place. Resettlement, meanwhile, provided a solution for 102,800 refugees.
