14th Supercentenarian Seminar

 Collecting and analysing international data on supercentenarians (individuals who lived 110 years or more) is crucial to gather information needed to measure the age-specific mortality risks at very old age and to select the best models to adjust life tables at the oldest ages. Two challenges have to be faced: how to increase the number of observations at ages when they become very rare, and to strictly check the quality of the information at ages when age exaggeration can be frequent. For two decades an international group of researchers explored that field, by building the International Database on Longevity (IDL) and producing papers and books through their participation to the first 13 seminars.
