This ethnographic exploration of contemporary spaces of homelessness takes an expanded view of homeless space, threading together experiences of organizational spaces, routes taken through the city and the occupation of public space. Through engaging with participants' accounts of movement and place, the book argues that young homeless people become fixed in mobility, a condition that impacts on both everyday life and possible futures. Based on an innovative multi-method study of a day centre in London for young homeless people, the book contextualizes spaces of homelessness within the social relations and flows of people that produce the world city. The book considers how the biographical and everyday trajectories of young homeless people intersect with place attachments and forms of governance to produce urban homeless spaces. It provides a new angle on the city made by movement, foregrounding the impact of mobilities shaped by loss, violence and the search for opportunity. The book draws on mental maps, photography, interviews and observation in order to produce an engaging and rich ethnographic account of young homeless people in the city.
