Description: Discussion and critique of an earlier paper IDL, the International Database on Longevity by Jean-Marie Robine. From 2005 Living to 100 and Beyond Monograph, M-LI05-1.

Description: This is a paper from the session on Shape of Mortality at Old Ages at the January 15-18, 2023, 2023 Living to 100 Symposium in Orlando, Florida.

Description: Estimation of hazard rates at extremely old ages poses serious challenges to researchers: 1 The observed mortality deceleration may be at least partially an artifact of mixing different birth cohorts with different mortality heterogeneity effect 2 Standard assumptions of hazard rate estimates may be invalid when risk of death is extremely high at old ages 3 Ages of very old people may be exaggerated. In this paper we propose an alternative approach, which gives an opportunity to resolve the first two problems by compiling data for more homogeneous single-year birth cohorts with hazard rates measured at narrow monthly age intervals. Possible ways of resolving the third problem of hazard rate estimation were elaborated.

Description: Centenarians persons living to age 100 and over represent a population that could be useful in identifying factors leading to long life and avoidance of fatal diseases. This study explores whether people living to 100 and beyond were any different from their peers at their middle age 30 years in terms of their physical characteristics height and body build, occupation and marital status.

Description: We suggest a new method of latent variable analysis and apply it for describing mortality changes in developed countries over the period of 1900--2014.

Description: Presented at January 2011 Living to 100 Symposium. This study explores the effects of parental age at a person's birth and the month of birth on chances of survival to age 100.

Description: This is one of eight essays from the collection: 2020 Living to 100 Essays.

Description: In this project the researchers explored the new opportunities provided by the ongoing revolution in information technology for studies of exceptional human longevity. Methodologies and interpretation of the results were presented.
