An intimate investigation of the world’s largest experiment in social engineering, revealing how its effects will shape China for decades to come, and what that means for the rest of the world When Communist Party leaders adopted the one-child policy in 1980, they hoped curbing birth-rates would help lift China’s poorest and increase the country’s global stature. But at what cost? Now, as China closes the book on the policy after more than three decades, it faces a population grown too old and too male, with a vastly diminished supply of young workers. Mei Fong has spent years documenting the policy’s repercussions on every sector of Chinese society. In One Child, she explores its true human impact, traveling across China to meet the people who live with its consequences.
