With eye-opening statistics, original data, and vivid portraits of people who live alone, renowned sociologist Eric Klinenberg upends conventional wisdom to deliver the definitive take on how the rise of going solo is transforming the American experience. Klinenberg shows that most single dwellers-whether in their twenties or eighties-are deeply engaged in social and civic life. There's even evidence that people who live alone enjoy better mental health and have more environmentally sustainable lifestyles. Drawing on more than three hundred in-depth interviews, Klinenberg presents a revelatory examination of the most significant demographic shift since the baby boom and offers surprising insights on the benefits of this epochal change.
