Determinants of family size in rural Galicia (Spain)
Abstract:
"The determinants of complete family size and offspring survival were assessed by means of family reconstitution data from 19th and 20th century rural [populations] of Northwest Spain. The reproductive performances of families were submitted to a stepwise regression analysis in which the number of children born alive and those surviving to reproductive age per family were taken as dependent variables, while 13 other variables were defined as independent. Infant mortality appears to explain most fertility variation; an earlier marital age and at first maternity leads to an increased family size. Survival seems to be the result of the apposite interaction of both fertility and mortality in early childhood."
