The terms historically used to describe them include "bums," "hoboes," "migrants," "street people," "transients," "tramps," and "vagrants." Just as varied as the words we have used to describe them are the reasons many people have found themselves living in the land of opportunity without permanent residence. The book considers homelessness and its distinctive character in three periods of American history: the era of tramps and hoboes in the late 1800s–early 1900s, the era of transients and migrants in the 1930s, and the era of homeless and "street" people in the last 40 years. It clarifies the multiple meanings of the word "homeless" today and demonstrates that homelessness is a symptom of more than one problem, leading to confusion about the issue of homelessness and hampering attempts to reduce its occurrence. Author Neil Larry Shumsky, PhD, also postulates that the treatment of homelessness in England before the colonization of North America laid the foundation of pervasive American attitudes and practices.

Covering the entire period from the colonial era to the late twentieth century, this book is the first scholarly history of the homeless in America. Drawing on sources that include records of charitable organizations, sociological studies, and numerous memoirs of formerly homeless persons, Kusmer demonstrates that the homeless have been a significant presence on the American scene for over two hundred years. He probes the history of homelessness from a variety of angles, showing why people become homeless; how charities and public authorities dealt with this social problem; and the diverse ways in which different class, ethnic, and racial groups perceived and responded to homelessness. Kusmer demonstrates that, despite the common perception of the homeless as a deviant group, they have always had much in common with the average American. Focusing on the millions who suffered downward mobility, Down and Out, On the Road provides a unique view of the evolution of American society and raises disturbing questions about the repeated failure to face and solve the problem of homelessness.
