In theory these are all Sudanese refugees from Darfur although you would hear about the odd Chadian who had also somehow registered and was living in the camp. The reality is that the existence in these camps could be better - or at least safer - than life in the average rural Chadian village. One of the most shocking things for a newcomer like me was the normalcy of the camps and the very humble resilience of the refugees. It's not all 'crushed defeat' and 'desperate horror' although that exists. But people also get happy, sad, confused, hopeful, married, angry and so on.
