Health and Mortality Elderly Populations Determinants and Implications
2015/6/25
Until very recently it was the conventional wisdom among demographers in low mortality countries that little scope was left for further decreases in mortality and increases in life expectancy at the o...
Quantifying policy tradeoffs to support aging populations
aging labor force participation rates normal pension age pensions retirement policy
2014/11/26
Background: Coping with aging populations is a challenge for most developed countries. Supporting non-working adults can create an unsustainable burden on those working. One way of dealing with this i...
An application of MCMC simulation in mortality projection for populations with limited data
Bayesian MCMC modelling mortality projection WinBUGS
2014/11/26
Objective: IIn this paper, we investigate the use of Bayesian modeling and Markov chain Monte Carlo (MCMC) simulation, via the software WinBUGS, to project future mortality for populations with limite...
Application of the modified PGW method for determining the smoking attributable fraction of deaths in New Zealand Maori, Pacific and non-Maori non-Pacific populations

2014/11/24
Background: Preston, Glei and Wilmoth recently proposed a new method for estimating smoking-attributable mortality in high income countries and an improvement to the method was proposed by Rostron. Th...
Stationary populations with below-replacement fertility
Austria below replacement fertility dependency ratios formal demography immigration stationary population
2014/11/20
Background: A population with sustained below-replacement fertility and constant immigration eventually becomes stationary. Stationary-through-immigration (SI) populations have unusual age structures ...

2014/11/20
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...
Sampling and Surveying Hard-to-Reach Populations for Demographic Research: A Study of Female Labor Migrants in Moscow, Russia
Central Asia migration Russia sampling survey methodology
2014/11/20
Because household-based survey designs are notoriously ineffective in studying hard-to-reach groups such as irregular migrants, these groups, however numerically large they may be, are rarely represen...
Age-decomposition of a difference between two populations for any life-table quantity in Excel
Age-decomposition difference two populations any life-table quantity Excel
2014/3/21
We provide a simple VBA/Excel program that decomposes by age a difference between two values of a life-table based quantity. For example, one might want to know what are contributions of different age...

The effect of changes in fertility on the age distribution of stable populations
age distribution population dynamics stable population
2009/5/31
When fertility increases in a previously stable population, the new stable population will be younger than the old one, and the two age distributions will cross at the mean age of the populations.
Using spatial statistics to infer scales of demographic connectivity between populations of the blue mussel, Mytilus spp.
Using spatial statistics infer scales demographic connectivity populations of the blue mussel Mytilus spp.
2014/4/18
We conducted a large-scale survey of blue mussel (Mytilus spp.) populations and recruitment along 100 km of the Southern shore of the St. Lawrence Estuary, Que′bec, Canada. By taking advantage of the ...
