Arriaga Meets Kitagawa. Life Expectancy Decomposition With Population Subgroups
An Arriaga decomposition partitions differences in life expectancy into contributions from mortality rate differences in each age. A Kitagawa decomposition partitions a difference between two weighted means into effects from differences in structure and from differences in each element of the weighted value. Life expectancy differences between like‐defined subpopulations can be decomposed using the Arriaga method, or a different suitable decompos…
All-cause and cause-specific mortality attributable to educational inequalities in Spain
Educational inequality remains a major public health challenge; its population-level impact on mortality is higher compared to the impact of smoking. Public health interventions addressing gender-specific social determinants of inequalities in health have a great potential for reducing mortality
Spatial Trends in Mortality Convergence
Spatial differences in mortality are a significant source of inequality in low-mortality countries and are important for public health, regional planning, and subnational population forecasts. Long-term trends in geographic mortality inequalities remain poorly understood, especially from a comparative perspective. In this study, we examine trends in subnational mortality differences in France, Italy, and Spain from 1975 to 2019. We study whether …
Evolution of Widowhood Lifespan and Its Gender and Educational Inequalities in Finland Over Three Decades
Widowhood is a disruptive life event, and in aging societies, increased numbers of individuals are potentially exposed to it. Yet, we lack a comprehensive understanding of the demography of widowhood. Using total population data with information on marital and cohabiting unions, discrete-time event-history analysis, and incidence-based multistate life tables, we analyze lifetime risk of widowhood, mean age at becoming widowed, widowhood expectanc…
Multistate analysis and decomposition of disability-free life expectancy trends at mid-to-older ages in Italy, 2004-19
Italy has witnessed increases in life expectancy and population ageing, raising concerns about their impact on population health. Disability status greatly affects the participation of mid-to-older-aged adults in various aspects of life. We examine the long-term trend in disability-free life expectancy (DFLE) in Italy, over three different periods between 2004 and 2019, and explore disability dynamics (onset and recovery) and changes in disabilit…
Healthy Lifespan Statistics Derived From Cross-Sectional Prevalence Data Using the Sullivan Method are Informative Summary Measures of Population Health
Health expectancy (HE), commonly derived from cross-sectional prevalence data using the Sullivan method, serves as the most frequently used summary measure of population health. Like lifespan distribution statistics, which are often discussed alongside life expectancy (LE) in demographic studies, analogous statistics on healthy lifespans can provide valuable information on population health. We examine whether healthy lifespan distribution statis…
Decomposition of Differentials in Health Expectancies From Multistate Life Tables
Multistate modeling is a commonly used method to compute healthy life expectancy. However, there is currently no analytical method to decompose the components of differentials in summary measures calculated from multistate models. In this research note, we propose a derivative-based method to decompose the differentials in population-based health expectancies estimated via a multistate model into two main components: the proportion resulting from…
Bayesian implementation of Rogers-Castro model migration schedules
BACKGROUND: The Rogers–Castro model migration schedule is a key model for migration trends over the life course. It is applied in a wide variety of settings by demographers to examine the relationship between age and migration intensity. This model is nonlinear and can have up to 13 parameters, which can make estimation difficult. Existing techniques for parameter estimation can lead to issues such as nonconvergence, sensitivity to initial values…

La surmortalité des jeunes adultes est-elle naturelle
Une hausse temporaire du risque de décès au moment de l’entrée dans l’âge adulte a été observée dans de nombreuses populations sans qu’une explication n’émerge clairement jusqu’ici. Plusieurs études récentes permettent cependant de mieux cerner les principales caractéristiques de ce phénomène, qui s’avère historiquement non universel, davantage masculin sans toutefois que les femmes y échappent, et dominé par les morts violentes
Exploring the demographic history of populations with enhanced Lexis surfaces
Lexis surfaces are widely used to analyze demographic trends across periods, ages, and birth cohorts. When used to visualize rates or trends, these plots usually do not convey information about population size. The failure to communicate population size in
Lexis fields
Lexis surfaces are visualizations designed to show how a given value changes over age and time. Vector ï¬ elds are two-dimensional representations of two variables: usually direction and speed (or force)

A Cause-of-Death Decomposition of Young Adult Excess Mortality
We propose a method to decompose the young adult mortality hump by cause of death. This method is based on a flexible shape decomposition of mortality rates that separates cause-of-death contributions to the hump from senescent mortality. We apply the method to U.S. males and females from 1959 to 2015. Results show divergence between time trends of hump and observed deaths, both for all-cause and cause-specific mortality. The study of the hump sh…
Symmetries between life lived and left in finite stationary populations
The Brouard-Carey equality describes the symmetries between the distribution of life lived and life left in stationary populations. This result was formally proved for populations of infinite size and continuous time, and a subsequent attempt to prove it f
The force of mortality by life lived is the force of increment by life left in stationary populations
BACKGROUND: The age distribution and remaining lifespan distribution are identical in stationary populations. The life table survival function is proportional to the age distribution in stationary populations. OBJECTIVE: We provide an alternative interpretation of the life table when viewed by remaining years of life. CONCLUSIONS: The functions describing the mortality of birth cohorts over age are identical to the functions describing the growth…
