With the collapse of the Soviet Union, Caucasian countries experienced remarkable migration flows, political conflicts, and deterioration of civil registration systems. The reassessment of Armenian and Georgian population after censuses carried out in the early 2000s enables to re-estimate...

It has been established that under certain mortality assumptions, the current value of the Cross-sectional Average length of Life (CAL) is equal to the life expectancy for the cohort currently reaching its life expectancy. This correspondence is important, because the life expectancy for the...

The standard period life table is based entirely on the death probabilities of the given period. Popular (not expert) usage of life expectancies from a period table typically ignores the fact that the expectancies make no allowance for future declines in mortality rates. But the historical...

Using the age- and sex-specific data of 14 developed countries, we compare the point and interval forecast accuracy and bias of ten principal component methods for forecasting mortality rates and life expectancy. The ten methods are variants and extensions of the Lee-Carter method. Based on...

As part of developing the new, so-called pace-shape framework of aging, where pace is measured by life-expectancy, in this paper we systematically investigate how perturbations in mortality affect life-expectancy.
