VII. OTHER GROUPS OR PERSONS OF CONCERN As a humanitarian agency, UNHCR often provides protection and/or assistance to certain population categories that it considers to be ‘of concern’ but which do not fall into any of the other population categories. T he activities undertaken for such groups by UNHCR are based exclusively on humanitarian grounds. Typical examples of such groups include former refugees in need of assistance to be locally integrated or rejected asylum-seekers whom UNHCR has determined are in need of humanitarian assistance. In addition, host populations who are directly or indirectly affected by an influx of displaced people may fall under this category. By the end of 2015, 870,700 individuals had been reported as other groups or persons of concern, compared to 1.1 million a year earlier. This includes 180,000 Ugandan nationals who reside in refugeehosting communities benefiting from UNHCRassisted programmes such as education, health, water, and sanitation. In addition, some 162,300 individuals are former Burundian refugees who have naturalized and reside in Tanzania; overall, Tanzania reported 168,600 people considered ‘others of concern’ at the end of 2015. Some 150,300 ‘others of concern’ were Afghans, made up of former refugees who have returned home but continue to have protection and economic needs similar to refugees. In order to ensure their reintegration into their society – often in the face of difficult economic situations, lack of comprehensive reintegration measures, or continuing poor security – UNHCR provides additional support to the most vulnerable parts of these populations. People in the three groups detailed above constitute 57 per cent of the other groups or persons of concern to UNHCR. Data on other populations of other groups or populations of concern were reported by 47 UNHCR offices in 2015. ● UNHCR Global Trends 2015 49
