This book investigates the future of the family as a foundational social institution by analyzing the causes and implications of its decline in advanced Western societies. David Popenoe, a prominent sociologist, utilizes a comparative historical framework to examine shifting family structures in the United States, New Zealand, and Switzerland. He argues that the erosion of traditional family units is a measurable phenomenon with significant social consequences, positioning Sweden as a primary case study for the most advanced stages of this decline.
