“…This study revealed greater lifespan variability for sisters than for brothers, corroborating observations from Desjardins and Charbonneau (1990) of a higher correlation in ages at death among brothers than among sisters. Mazan and Gagnon (2007) explored the same relationships for individuals born between 1625 and 1704 and also found a high dependency in ages at death among siblings, with reduction in mortality risks of 2.1% and 1.6%, respectively, for men and women, for each additional year of increase in the average age at death among their siblings.…”

“…Par plusieurs techniques, les mêmes relations ont été mises en évidence et ont souvent confi rmé les résultats de diverses études. Effec ti vement, comme plusieurs autres chercheurs (Pearl et Pearl, 1934;Swedlund et al, 1983;Bocket-Appel et Jakobi, 1990et 1991Desjardins et Charbonneau, 1990;Cournil, 2000;Gudmundsson et al, 2000;Carey et Judge, 2001;Gavrilov et Gavrilova, 2001a;Westendorp et Kirkwood, 2001), nous obtenons des résul tats qui démontrent que l'âge des parents au décès infl ue sur l'âge au décès de leurs enfants, particuliè rement chez ceux qui ont atteint des âges très élevés.…”

“…Ces résultats corroborent ceux de nombreuses études qui ont conclu à une relation positive entre l'âge au décès des parents et celui de leurs enfants (Beeton et Pearson, 1901;Bell, 1918;Pearl, 1931;Pearl et Pearl, 1934;Bocket-Appel et Jakobi, 1990et 1991Desjardins et Charbonneau, 1990;Cournil, 2000;Gavrilov et Gavrilova, 2001a;Carey et Judge, 2001). Plus les parents vivent vieux, plus la probabilité que leurs enfants en fassent autant est grande.…”

Par l’entremise du Registre de la population du Québec ancien (RPQA), banque de données élaborée dans le cadre du Programme de recherche en démographie historique, nous avons observé l’existence d’une composante familiale de la longévité. En effet, l’âge au décès des parents semble influencer l’âge au décès de leurs fils et filles, particulièrement pour les parents décédés après 70 ans. Nous avons aussi observé une convergence significative de l’âge au décès dans les fratries. Cependant, il existe également une relation entre les âges au décès des conjoints, ce qui laisse supposer que la composante familiale est due à la part environnementale de l’héritabilité plutôt qu’à la part génétique.For a long time, people have had a belief in a form of heritability in regard to longevity. According to this belief, reaching very great ages would be specific to some families. By using the Registre de la population du Québec ancien (RPQA), a database put together by the Programme de recherche en démographie historique (PRDH), we have established the existence of a familial component of human longevity. Indeed, our results suggest that the parents’ ages at death could have had a significant influence on their children’s ages at death, particularly for parents who died at age 70 or over. Moreover, our analysis revealed a significant association between brothers’ and sisters’ ages at death. However, there is also a clear relationship between spouses’ ages at death, which implies that the familial component of longevity could be more strongly related to the environmental component of heritability than to its genetic component

“…Biodemographic studies going back a century or more have provided much evidence that longevity runs in families, as similarities were found between close relatives" ages at death (Desjardins and Charbonneau 1990). But in these studies it has always been difficult to distinguish what is owed to genes from what is owed to environmental influences-shared as they are, to a large extent, by relatives.…”

For a long time, historians were not at ease with the unpredictability of crisis mortality: "Epidemic disease, when it did become decisive in peace or in war, ran counter to the effort to make the past intelligible" (McNeill 1998). Yet, with hindsight-history is always about hindsight, and historical demography is no exception-these events, while they would still be unpredictable in the details of their occurrence, are nevertheless interpretable, and many of their distinctive features are no longer within the realm of the unknown. We now know a great deal about the dynamics involved in historical epidemiological processes, such as the rate of spread of an infectious disease and the factors underlying its incidence or virulence. Thanks to the increasing availability of historical longitudinal micro-data, we also know more about the factors modulating the individual risk during an outbreak, how sex and age patterns of mortality are modified, and how these patterns differ from other times when mortality is simply high, but for other reasons. Who were at the highest risk? Males or females? At what ages? We can now answer these questions with relative confidence.
