About one-fifth of the world's population comprises what the United Nations calls the global underclass.
Who belongs to the global underclass?
The underclass is the portion of society that lies beneath the majority of the working class in a hierarchy of social standing. In the social sciences, there is a long history of the general hypothesis that a class structure contains a population below the working class (for example, lumpenproletariat).
Members of the underclass are frequently defined as those who do not work and depend on public assistance as their primary source of income.
