IDPs are often the victims of direct or indirect discrimination in host communities based on their situation or categorization as IDPs. In some cases this discrimination may be based on ethnic or other differences, while in others it is due to more structural problems. In the context of his country visits, the Special Rapporteur has found that IDPs are often denied access to basic services such as primary education and health services, due to the fact that local schools or health facilities are already underfunded or overcrowded, or for purely bureaucratic reasons. In these contexts, local health and educational institutions may request proof of residency or special fees from IDP families (for services normally free of charge), so as to be able to effectively expand their services to them. Such situations reflect the need for more effective coordination and timely financial transfer systems between central and local authorities, including the areas from which IDPs fled, which can take into account a local influx of IDPs and their related needs.
