What happens to a community when the majority of young people leave their homes to pursue an education? From a Trickle to a Torrent documents the demographic and social consequences of educational migration from Nubri, a Tibetan enclave in the highlands of Nepal. The authors explore parents’ motivations for sending their children to distant schools and monasteries, social connections that shape migration pathways, young people’s estrangement from village life, and dilemmas that arise when educated individuals are unable or unwilling to return and reside in their native villages. Drawing on numerous decades of research, this study documents a transitional period when the future of a Himalayan society teeters on the brink of irreversible change.
