Using data from Germany, we examine if month of birth influences survival up to age 105. Since age reporting at the highest ages is notoriously unreliable we draw on age-validated information from a huge age validation project of 1487 alleged German semi-supercentenarians aged 105+. We use month...

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...

We present an analysis of birth seasonality in nine geographical regions within Austria for two time periods, 1881-1912 and 1947-1959. In the early period, geography, climate, and agricultural patterns were related to birth seasonality. By the later time period, these factors were no longer...

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...

By European standards, consensual first unions have been rare in Romania, and they remain so even though their incidence has increased by a factor of almost five since the early 1960s. Rates of conversion of consensual unions into marriages have been cut in half over the same four decades or so,...

Extending recent research on parental gender preferences in the Nordic countries, this study uses unique register data from Finland and Sweden (1971-1999) that provide us with the opportunity to compare childbearing dynamics and possible underlying sex preferences among natives and national...

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...

Empirical research investigating gender preferences for children and their implications for fertility decisions in advanced industrial societies is relatively scarce. Recent studies on this matter have presented ambiguous evidence regarding the existence as well as the direction such preferences...
