[Life expectancy for the regions of the Northwestern Federal District. Part 2: Dynamics of old age threshold.]

The paper continues the study of the population ageing in the regions of the Northwestern Federal District. It characterized population ageing based on prospective ageing indicators that take into account remaining life expectancy. The dynamics of life expectancy (LE) at birth was analyzed. A computation and comparative analysis of the old age threshold for the regions that are part of the Northwestern Federal District have been carried out. A comparative analysis of ageing indicators - traditional and prospective (the proportion of the elderly and the share of the population above the old age threshold) was carried out. It has been found that there are no fundamental differences in the dynamics of life expectancy in older ages, as well as in the of old age threshold, between the regions considered. It is shown that for the male population in almost all regions in 2021, the value of the old age threshold is below 60 years, while for the female population the opposite inequality is observed. Thus, in 2021, the share of men over the old age threshold exceeds the proportion of the elderly in almost all regions considered, and for the female population, the share of the elderly is expected to be higher than the values of the prospective indicator.
