Thank you very much for your question.
Internal displacement affects the full range of human rights, but I would say that the first things that come to mind are the right to housing, the right to a livelihood, the right to health care and the right to education.
Numerous studies have shown that displaced children often end up out of the school system, for example. This means they are deprived of their right to education. Studies have also shown that displaced people often have trouble accessing health care.
So I would say that access to education, access to health care, access to water and food, of course, access to housing and access to livelihoods are the main rights affected by internal displacement. In any case, all human rights are affected, generally speaking.
