Abstract

The use of family reconstructed database represents a technique widely applied both in historical demography and in genetic. However in both fields few large family reconstructed databases are suitable for the study of longevity. The following communication aims to present a unique database build using data collected on a population experiencing exceptional longevity in Sardinia (Italy). Each individual is followed from birth to death, going through marriage and family formation. The Villagrande Longevity Database (VILD) includes all newborns in the village in a period of 50 years (1866-1915). The level of coverage reached is exceptionally high, thanks to the completeness of data sources used and the high endogamy registered. By considering family links within the whole population, this database enables to consider in the analysis also the effect of familial characteristics toward survival and extreme longevity. Preliminary results are presented in comparison with finding from other studies on human survival.
