A chilling and famous short story by Vonnegut, published in 1962. The title refers to the telephone number one dials to schedule an assisted suicide with the Federal Bureau of Termination. The setting is a society in which aging has been cured, individuals have indefinite lifespans, and population control is used to limit the population of the United States to 40 million. This is maintained through a combination of infanticide and government-assisted suicide. In short, in order for someone to be born, someone must first volunteer to die. As a result, births are few and far between, and deaths occur primarily by accident.
