A new perspective on population aging

Sanderson, Warren C.; Scherbov, Sergei - In: Demographic Research 16 (2007) 2, pp. 27-58

In Sanderson and Scherbov (2005) we introduced a new forward-looking definition of age and argued that its use, along with the traditional backward-looking concept of age, provides a more informative basis upon which to discuss population aging. Age is a measure of how many years a person has...

On stochastic comparisons of population age structures and life expectancies

Finkelstein, Maxim - In: Demographic Research 13 (2005) 6, pp. 143-162

Cohort measures, describing a lifetime random variable are easily and unambiguously obtained using standard tools. On the contrary, the lifetime random variable, and therefore life expectancy, for the period setting cannot be unambiguously defined without additional simplifying assumptions. For...

Algorithm for decomposition of differences between aggregate demographic measures and its application to life expectancies, healthy life expectancies, parity-progression ratios and total fertility rates

A comparison of different methods for decomposition of changes in expectation of life at birth and differentials in life expectancy at birth

Ponnapalli, K. Murthy - In: Demographic Research 12 (2005) 7, pp. 141-172

Several methods were proposed to decompose the difference between two life expectancies at birth into the contribution by different age groups. In this study an attempt has been made to compare different methods with that of Chandra Sekar (1949) method. The methodologies suggested by Arriaga,...

Historical Addendum to "Life lived equals life left in stationary populations"

Goldstein, Joshua - In: Demographic Research 26 (2012) 7, pp. 167-172

This note provides some earlier history of the relationship given in FormalRelationships1, "Life left equals life lived in stationary populations," (Goldstein2009) and shows that while the expectation of life at the mean age of the population is close to the mean age, this is not exactly so.
