Family network and mortality: survival chances through the lifespan of an entire age cohort.
This study relates certain family network variables (martial status and number of children) to chances of survival. Through multivariate analysis, survival is also related to social class, social mobility, migration and local environment, and legitimacy of birth. All persons in a local birth cohort born in the years 1902 and 1903 were followed in population records from birth until eighty years of age. The group comprised 487 individuals with a dropout rate of 4 percent. Univariate survival analysis between twenty to eighty years of age showed widows and also divorced women to have a significantly higher survival than those still married and never married. Never married men and women had the lowest survival rates. The number of children was not associated with survival for neither men nor women when controlled for marital status. Multiple regression survival analysis showed different patterns for males and females. The risk of not surviving to eighty years of age for men resulted from a combination of being single, downward social mobility, a father in the manual working class group and few children, with being single as the strongest predictor. For women the strongest predictor for death before eighty was the category single and/or married (as opposed to earlier married). The combination of being single/married, high migration, earlier life mainly in rural areas, and having few children were predictors in the model of death before eighty. Thus, for both men and women marital status was the strongest predictor for survival but in different ways.
