Background and senescent component of adult mortality and its connection to mortality shifting

Abstract

Because of the already very low level of mortality at lower ages, the mortality analysis started to be focused mainly on higher ages and the population group of the "oldest-old". Within the analysis of the force of mortality the decomposition of the total mortality into two different components could be seen to be applied (among other methods) - decomposition to the senescent and background mortality.

Both these components could be studied separately.
