The HSN Long-Lives 2020_01 is based on a subsample of the HSN life courses. From the 37,137 original HSN RPs, 884 RPs who died at 80 years or beyond (case group) and 442 RPs who died between 40 and 59 years (control group) were selected. These RPs were born between 1860 and 1875 and in total represent 1,326 families. The pedigrees were extended until the living descendants for all 1,326 families were identified. Information on the pedigrees is shown in HSN LongLives 2020_01, F2 and F3 contain additional information on individuals from the second and third generation. Conform European and Dutch privacy legislation, any identifying information of individuals and all living individuals were removed from the full HSN Long-Lives subsample database.
