Migration and fertility in Ticino.

Summary Migration in the Swiss canton of Ticino is one example of the wide variety of demographic systems that existed in pre-industrial Europe. The continuous movement of men was a consequence of economic, social and geographic conditions which restricted the demand for labour. Seasonal migration and overseas migration were both sex and age selective. They resulted in an imbalance of the sex ratio and a remarkably low female nuptiality. They also reduced fertility within marriage by separating husbands and wives during their childbearing years. The effect of long, medium and short-term migration on fertility can be isolated from census and vital registration sources.
