Young Afghan boys and teenagers have to endure the cold in Calais, France. Some sleep under bridges at night while others find accomodation through an organization defending the rights of migrants. UNHCR / H. CAUX 59 years, whereas 5 per cent were 60 years or older. Among refugees and people in refugee-like situations, children constituted 41 per cent of the population. Their proportion was significantly higher among those refugees who returned home in 2009 (54%). This poses considerable challenges for reintegration programmes, in particular with respect to education in those locations where schools have been damaged or destroyed. Children constituted only 27 per cent of asylum-seekers, a population often largely composed of single men particularly in the industrialized world. Moreover, populations in camps were younger (52 per cent children) than in urban areas (43 per cent children). The availability of information according to age breakdown was particularly limited for developed countries in Europe, North America and Oceania. Thus, the figures above cannot be considered fully representative of the entire population under UNHCR’s responsibility. Location characteristics Information collected about the location characteristics of where persons of concern reside is broken down by the following categories: camps/settlements/centres; urban areas; and rural areas. The last two categories usually correspond to people privately accommodated with host families or living on their own. In 2009, the type of location was reported for some 15 million persons of concern residing mainly in non-industrialized countries. (19) This represents close to 41 per cent of the total population of concern. With some 78 per cent coverage (8.2 million people), the availability of location data was higher for refugees than for any other group. Of these, 2.5 million people were residing in organized camps or centres (30%) and 4.8 million (58%) in Distribution of refugees by type of location * | end-2009 Fig 9 58% 50% 50% 34% 30% 2007 30% 2008 % Camps 2009 % Urban * Excludes unknown locations 19 Even though UNHCR offices reported the information on the location for a total of 29 million persons of concern, the location or settlement type for 14 million persons (mostly IDPs) was unclear or a mixture of types. 2009 Global Trends 15
