The term "underclass" refers to the part of the population which occupies the lowest level in a social hierarchy (under the working class) in terms of wealth and opportunities. The term is very controversial, and is often criticized in the social sciences.

It includes people with characteristics such as being unemployed, being homeless, working in extremely precarious conditions, having very little formal education or suffering from mental illnesses or substance abuse.
