The causes of homelessness and determining how best to assist those who find themselves homeless became particularly prominent, visible issues in the 1980s. The concept of homelessness may seem like a straightforward one, with individuals and families who have no place to live falling within the definition.

This book describes existing federal programs that provide targeted assistance to homeless individuals and families and the current issues related to homelessness, including the economic downturn.
