Statelessness is a particularly vulnerable condition in which individuals and peoples can encounter themselves in a situation where they are not considered as nationals of any state. Among a variety of factors, war, discrimination against minority groups, gender discrimination affecting the possibility to pass nationality to children, failure in the legislation of new states, and even climate change menacing the very existence of some states, can produce stateless individuals. Also, there are cases in which individuals and groups for various reasons could be unwilling to make use of their own citizenship. This report presents the results of both a content analyses of the United Nations (UN) official documents including discussions of “Statelessness”, since 2000, and a discourse analysis of thirty-four documents of the UN Security Council (UNSC), in which the UN permanent and non-permanent members considered this issue in the agenda.
