Family structures and its impacts on children’s education attainment
Despite the recent expansion of education, children from lower socioeconomic backgrounds are still less likely to attend university than children from wealthier families. This persisting inequality in educational attainment led social scientists to explore a range of possible factors behind these unequal opportunities. Given that in many countries it is very common for children from lower socioeconomic backgrounds to live without at least one parent, family structure has often been held responsible for explaining part of the inequality of opportunities between socioeconomic groups. A recent study conducted by Fabrizio Bernardi and Diederik Boertien suggests that this claim may be unwarranted. [...]
Divorce rates in Western countries have been increasing in recent decades and more children are also born to parents who never cohabitate.  As a result, more and more children are living in joint or sole physical custody.  [...]
Un groupe de chercheurs a identifié 12 régions spécifiques de notre ADN qui sont fortement liées à notre âge à la naissance de notre premier enfant, ainsi qu’au nombre total d’enfants que l’on aura durant notre vie. [...]
Forscher haben 12 Bereiche in der DNA-Sequenz identifiziert, die stabil damit verbunden sind, in welchem Alter wir unser erstes Kind und wie viele Kinder wir im Laufe unseres Lebens haben. [...]
Researchers have identified 12 specific areas of the DNA sequence that are robustly related with the age at which we have our first child, and the total number of children we have during the course of our life. [...]
Long-term effects of attending preschool
It has been proven that preschool attendance improves certain short-term cognitive outcomes of children, such as early literacy, early number concepts, and health. However, very little is known about the long-term effects of preschool. [...]
Ageing without children
In recent years, the number of ageing adults in societies has increased significantly. At the same time, even countries with generous social support systems have begun shifting care obligations away from the state, emphasizing the need for individual responsibility. The idea falls under the assumption that adult children will step in as the need for care arises. But what does this mean for individuals who, either voluntarily or involuntarily, do not have children in old age? In a recent article, Katya Ivanova and Pearl Dykstra identify and explore key issues that arise when considering the care needs of aging nonparents. [...]
Parental supervision and risky behaviour of teenagers in the U.S.
When tackling risky behaviour of adolescents, are mothers and fathers equally capable of influencing their child? While the literature has pointed to a mitigating effect of parental supervision on adolescent risky behaviour, studies thus far did not differentiate between fathers and mothers. [...]
New evidence from Switzerland
The role of income and employment on fertility patterns has already been extensively explored in the existing literature. However, empirical evidence for such effects is surprisingly scarce for Switzerland. In this recent study, Doris Hanappi, Valérie-Anne Ryser and Laura Bernardi examine the way perceived job quality is associated with the intention to have a child for men and women in Switzerland. The authors also explored whether job quality carries the same weight when considering first and subsequent child intentions, and whether the belief that children suffer by having a working mother changes the effects of job quality on the childbearing intentions of individuals.

Immigrant generations and partnership dynamics in France
During the past 50 years, marital trends in Europe have changed significantly, particularly in France, where family formation has been postponed, the number of marriages has declined and cohabitation has increased. Simultaneously, for some time now, France has been a country of immigration, welcoming immigrants from a wide variety of countries and regions where partnership patterns are highly diverse. How are these two trends connected? In her study, Ariane Pailhé compares partnership dynamics between immigrants and the native French population. Using data from the Trajectories and Origins (TeO) survey, she explores whether the change in family patterns among the French population have taken place among first and second generation immigrants, as well as across immigrant groups.
