Description: Presented at Living to 100 and Beyond symposium 2002. Discussion on 'Living to Age 100 in Canada in 2000' by Doray and 'Oldest-Old Mortality Rates and the Gompertz Law: A Theoretical and Empirical Study Based on Four Countries' by Yue papers.

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: 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: 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.
