The ratio (RMR) is the standard measure of sex differentials in mortality. It is commonly known that the RMR was historically small and increased throughout the 20th century. However, numerical properties might account for the trend in the RMR rather than sex differences in risk factors. In this...

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 paper aims at contributing to a proposal for the concept and content of the Contextual Database of the Generations and Gender Program. We develop guidelines for data collection by identifying the main focus, the key dimensions as well as the main data types of the GGP Contextual Database....

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...

The increasing recognition that the study of human behaviors has to take into account the multiple contexts in which they occur has opened a promising research avenue in social sciences. It also presents new challenges, e.g., to complement micro-level surveys with the collection of meaningful...

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...

As one aspect of the complex feature of longevity, gene-sex interaction plays an important role in influencing human life span. With advances in molecular genetics, more studies aimed at assessing gene-sex interaction are expected. New and valid statistical methods are needed. In this paper, we...

This paper outlines the concept and content of the Contextual Database of the international Generations and Gender Program and gives an overview of the context of demographic behavior in Bulgaria. The Contextual Database provides an instrument that together with the Generations and Gender Survey...

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...
