Abstract: We show existence and uniqueness of estimates for the growth parameter and the remaining life expectancy of elderly within the model of stable population with endogenous growth parameter. Results obtained point to possibility to estimate the growth parameter, assuming a graduated input data, from a general formal relation, without iterative or optimization procedures used. Presented results are of theoretical and practical importance in studying life expectancy and mortality of elderly.

Keywords: life expectancy, Malthusian parameter, stable population, age exaggeration.
