Analyzing the Trends of the Modal Age at Death Using the Linear Difference Model
Futoshi Ishii, National Institute of Population and Social Security Research, Japan
Recently, the modal age at death has been paid more attention as an indicator of longevity (Horiuchi et al. 2013). Although many studies have discussed the modal age at death, there have been few articles that examined decomposition analyses of the change of the modal age in terms of the shifting and/or the compression of the mortality curve. The author has proposed the Linear Difference (LD) model that is a shift-type adult mortality model and shown that the model has some advantages for the modeling of adult mortality for Japan and several EU countries compared to the decline-type model such as the Lee-Carter model (Ishii and Lanzieri 2013). In this paper, we propose a new decomposition method for the modal age at death using the LD model, and give decomposition analyses with the method.
