Fälldin was born in Högsjö parish, Ångermanland, the son of the farmer Nils Johan Fälldin and his wife Hulda (née Olsson). He grew up in a farming family in Ångermanland, and, in 1956, he and his wife, as a newlywed young couple, took over a small farm. However, the farming authorities did not approve the purchase, as the farm was considered too small and too run down for production, and so refused to provide farm subsidies. This fight led him into the youth branch of the Swedish agrarian party Farmers' League (Bondeförbundet), which in 1958 changed its name to the Centre Party. He and his family maintained their farm throughout his political life, and when he resigned from politics in 1985, he immediately returned to it.
