Emigrazione temporanea recente e di lungo corso a Giaglione (TO): 1858 e 1861

Migration is a reversible phenomenon that has interested to greater or lesser extent all human communities . Immigration allows not only to enrich the genetic pool of a population but also to import new behavioral patterns that may prove essential in the development and survival of the community. Emigration, despite impoverishing the genetic patrimony at first, may later establish a future enrichment for the population of origin, provided that emigration has the character of temporality: the individual migrants have the opportunity to form and grow in an environment different from the native one, importing new experiences in the community of origin , possibly accompanied by a allochthonous partner and thus contributing to the expansion of input genetic flow. The temporary migration is studied here through the population censuses of Giaglione (TO) in the years of transition from the state of Savoy (1858 ) to the Kingdom of Italy (1861). The family-based documentation is very detailed for both surveys and the censuses also included the "temporarily absents", together with information on their home and work.
