In this groundbreaking new text, general editor A. Javier Treviño, working with a panel of experts, thoroughly examines all aspects of social problems, providing a contemporary and authoritative introduction to the field. Each chapter is written by a specialist on that particular topic. This unique, contributed format ensures that the research and examples provided are the most current and relevant in the field. The chapters carefully follow a model framework to ensure consistency across the entire text and provide continuity for the reader. The text is framed around three major themes: intersectionality (the interplay of race, ethnicity, class, and gender), the global scope of many problems, and how researchers take an evidence-based approach to studying problems.
