““This volume aims to identify the resources and personal qualities that help disadvantaged youth, but also the barriers they face. It is a book about social stratification in the urban context, informed by the experience of the panel of Baltimore children whose life trajectories we tracked for nearly a quarter century from 1982 to 2006. They are an internally diverse group—black and white, mostly low income at the outset, but also some who began life in more favorable circumstances. The next section provides background on the project. The chapter concludes with an overview of the book.””
