Following Mao Zedong's December 1968 directive that it was 'very necessary for educated youth to go to the countryside', some 17 million urban secondary-school graduates, most aged between 15 and 23, were assigned to villages, state farms and frontier regions across China. The campaign closed urban schools and factories to a whole cohort, dispersed families, and tied those sent down to rural household registration that made return difficult; assignments continued after Mao's death and the movement was wound up around 1980, when large-scale returns to the cities began. Historians describe it as one of the largest state-organised population transfers of the twentieth century; participation was directed by the state rather than chosen, though pressure varied by city, family background and year, and a substantial minority of the eligible cohort was never sent. The returnees are widely referred to in China as the 'lost generation' for the schooling and careers forgone.
The Chinese Communist Party under Mao Zedong relocated urban secondary-school graduates to rural villages, state farms and border regions for "re-education by poor peasants"
China's population was about 785 million in 1968 with roughly 17-18% classed as urban under the hukou system, giving 130-140 million town and city dwellers. The sent-down cohort was drawn specifically from urban lower- and upper-middle-school graduates.
There was no significant death toll directly attributable to the rustication programme itself. Deaths occurred from accidents, illness and violence in the receiving areas, and the wider Cultural Revolution was lethal on a large scale, but the sources cited here do not attribute a mortality figure to the transfers.
