The longterm historical decline in infant mortality has been accompanied by increasing concentration of infant deaths at the earliest stages of infancy. The influence of prenatal and neonatal conditions has become increasingly dominant relative to postnatal conditions as external causes of death...

Patterns of diversity in age at death are examined using e†, a dispersion measure that also equals the average expected lifetime lost at death. We apply two methods for decomposing differences in e†. The first method estimates the contributions of average levels of mortality and mortality...

This study examines the relationship between growing inequality within the population, and the general mortality decline in Finland after 1971. The general mortality trend is considered as a simultaneous shift of population groups toward lower mortality over time, with the group-specific...

We study inter-individual variability in number of children among women. Concentration ratio (CR) and percentile measures are used. In most countries CR has increasing from cohorts of the 1930s-40s onward due to rise in childlessness. In cohorts of the early 1960s CR varies from 0.24 to 0.46...

Interpersonal relationships of support have been found to be an important factor in individual fertility intentions in Central and Eastern European countries. The foundations of this positive influence have not been well explored to date, however. We present a theoretical discussion on...

Models on the impact of social networks on reproductive behavior primarily address processes of interpersonal influence on fertility related values and utility perceptions and consider aspects of social support and social capital only to a small extend. On the basis of an exchange theoretical...

This paper presents a toolkit for measuring and analysing inter-individual inequality in length of life by Gini coefficient. Gini coefficient is treated as an additional function of the life table. A new method for the estimation of Gini coefficient from life table data has been developed and...

Research about fertility has focused in the main on studying separately the influences of communication networks and social capital on reproductive behavior, but it has rarely tried to integrate both network properties theoretically or analytically. We therefore discuss a general model of...

A general algorithm for the decomposition of differences between two values of an aggregate demographic measure in respect to age and other dimensions is proposed. It assumes that the aggregate measure is computed from similar matrices of discrete demographic data for two populations under...
