This chapter is concerned with youth homelessness and draws particularly on the last major survey of single homelessness conducted in England (Anderson et al. 1993). The first section of the chapter examines the different causes of youth homelessness. The following section considers the issues around defining and measuring youth homelessness in Britain. The final section examines the experiences and characteristics of young homeless people in Britain during the 1990s. The conclusion examines some of the issues surrounding effective intervention to counteract and prevent youth homelessness, a theme that is considered in more detail in the next chapter.
