The discussion concerning fertility in Singapore during the post-Second World War period has been confined to consideration of the reduction in total period fertility. Although a focus on period ferti...
Cohort Fertility Patterns in the Nordic Countries
cohort fertility educational attainment Nordic countries postponement recuperation

This paper uses two British birth cohorts, born in 1958 and 1970. There are substantial inter-cohort shifts in timing and context of becoming a parent and gender differences in timing. We use common c...
Cohort fertility patterns and breast cancer mortality among U.S. women, 1948-2003
age-period-cohort breast cancer mortality cohort fertility
2008/12/16
Epidemiological research has shown that women who have early and numerous births have reduced risks of being diagnosed with breast cancer. We use U.S. Vital Statistics and Census data and age-period-c...

Major changes in childbearing patterns are continuously taking place in the majority of low-fertility populations with postponement being virtually universal. Almost everywhere the two-child family be...
Found in translation? A cohort perspective on tempo-adjusted life expectancy
cohort life expectancy cohort-period translation life tables mathematical demography mortality tempo effects
2008/12/11
What does tempo-adjusted period life expectancy measure? Taking a cohort perspective, I show that under conditions of constant linear mortality shifts the tempo-adjusted period indicator translates ex...
Age-specific contributions to changes in the period and cohort life expectancy
age-specific decomposition cohort life expectancy gap and lag life expectancy mortality models period life expectancy
2008/12/11
Period life expectancy has increased more slowly than its cohort counterpart. This paper explores the differences between life expectancies at a given time (the gap) and the time required for period l...
Changing mortality and average cohort life expectancy
cohort life expectancy cross-sectional average length of life (CAL) life expectancy mortality mortality tempo period life expectancy
2008/12/11
Period life expectancy varies with changes in mortality, and should not be confused with the life expectancy of those alive during that period. Given past and likely future mortality changes, a recent...

In this paper I explore the formal relationship between period and cohort mortality, focusing on a comparison of measures of mean lifespan. I consider not only the usual measures (life expectancy at b...
Modelling regional variation of first-time births in Denmark 1980-1994 by an age-period-cohort model
age-period-cohort models Denmark fertility fertility rate nulliparous women regional
2008/12/11
Despite the small size of Denmark, there have traditionally been rather consistent regional differences in fertility rates. We apply the statistical age-period-cohort model to include the effect of th...

Background: Prior estimates of the Russian mortality by socio-demographic group revealed significant differentials around the censuses of 1979 and 1989, but these studies were based on different sourc...
A diminishing population whose every cohort more than replaces itself

2008/12/9
We observe that a dynamic population model can have period fertility that is always below replacement and cohort fertility that is always above replacement. We ask whether such a paradoxical populatio...
