[Mortality in past centuries]

"Mortality and life expectancy over a time period of 300 years were studied for a relatively large village population [in Germany]. From synchronous and diachronous comparisons of the data concerning different social classes of this village (subdivided according to their sex and age, social rank, number of children/family and birth rank, registration of orphans, half-orphans, illegitimate children as well as progeny of old parents and children with a high inbreeding degree, and interpretation of causes of death) significant differences in mortality were deduced."
