I assume someone in the 5th percentile of wealth is going to have very negative wealth which is only really possible in developed countries, eg an American medical student or a doctor who is part-way through paying off their loans, or someone suffering from massive credit card debt / car loans. (I think this isn’t really what you were thinking of though. I think the poorest people in the world still live, in many ways like medieval peasants except with much lower infant mortality and somewhat net food security)
