It is now more common for an American adult to live alone than with family or a roommate, and Klinenberg analyzes the challenges and opportunities these people face: young professionals who pay higher rent for the freedom and privacy of their own apartments; singles in their thirties and forties who refuse to compromise their career or lifestyle for an unsatisfying partner; divorced men and women who no longer believe that marriage is a reliable source of happiness or stability; and the elderly, most of whom prefer living by themselves to living with friends or their children. Living alone is more the rule than the exception in places like Manhattan, half of whose residents live by themselves, and many of America's largest cities, where more than a third of the population does. Drawing on over three hundred interviews with men and women of all ages and every class who live alone, Klinenberg reaches a startling conclusion: In a world of ubiquitous media and hyperconnectivity, this way of life helps us discover ourselves and appreciate the pleasure of good company.
