Age correspondence for different mortality regimes with and without the change point
The mortality rates are steadily declining with time. The remaining lifetime for e.g. 65 years old person even 20-30 years ago was substantially smaller than nowadays. Therefore, the age correspondence problem for populations in different mortality regimes is of interest. A simple solution, based on the equality of accumulated mortality rates (or, equivalently, on the equality of probabilities of survival) is considered. Furthermore, the mortality regime with a change point is defined and the procedure of age re-calculation after the change point is suggested. Two age re-calculation models (and their combination) are discussed: the first one accounts for wear accumulation in the process of aging and the other is characterized by a kind of memoryless property.
