Book excerpt: Social Problems in a Diverse Society provides students and instructors with a text that covers all the major social concerns we must deal with today. It focuses on the significance of racialization and ethnicity, age, sexual orientation, class, ability, and gender in understanding social problems in Canada and around the globe. Throughout the text, people--especially those from marginalized groups--are shown not merely as "victims" of social problems, but also as individual actors with agency who resist discrimination and inequality and seek to bring about change in families, schools, workplaces, and the larger society.
