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.
