The People of the Abyss is Jack London’s powerful nonfiction account of poverty and hardship in London’s East End at the beginning of the twentieth century. Living among the poor, London observed homelessness, hunger, overcrowding, unemployment, and the harsh conditions faced by working-class families. Through firsthand experiences and vivid descriptions, he exposes the social inequality hidden beneath the prosperity of the British capital. The book combines investigative reporting, personal narrative, and social criticism to examine how poverty affects dignity, health, and opportunity. It remains an important work of social observation and a compelling record of urban deprivation.
