Description: Discussion on Living to 100 Session 4B. Papers presented: Typology and Review of Measures of Human Aging, Longevity and Superlongevity with Applications to US Data and Some Implications for US Public Programs and, Mortality Measurements at Advanced Ages: A Study of the Social Security Master Death File

Description: Transcript of Session 3A from the 2008 Living to 100 Symposium discusses the use of mortality in social insurance systems in the US and Canada.

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.
