PopDigests are short, comprehensive summaries of research results with a link to the original publication (if accessible online). This allows population experts and other interested audiences to be able to easily access information to the latest research results. 

WhatsApp is currently the most popular messaging application with the largest name recognition, by far the largest user base, and the strongest corporate backing since its acquisition by Facebook in 2014. It allows people to easily share texts, pictures and audio files. [...]
Can couples who equally share domestic work maintain their egalitarian ways after the birth of their first child? And how is subjective satisfaction with work-life balance related to equal arrangements? Researchers María José González, Irene Lapuerta, Teresa Martín-García and Marta Seiz recently published a study analysing 31 dual-earner couples in Spain who had practiced an egalitarian division of household tasks during pregnancy. [...]
More and more people are living until the ages of 100 or 105, becoming so-called centenarians or semi-supercentenarians. Women are far more likely than men to reach this old age, but according to a new study by Graziella Caselli, Marco Battaglini and Giorgia Capacci, the age gap is likely to grow smaller in the following decades. [...]
Childless men and women have an overall higher mortality than adults with children, meaning that they die earlier, recent studies show. Mothers and fathers with two biological children have the lowest mortality risks, but it increases for parents with three or more biological children. What are the explanations for the relationship between having children and mortality risks? In a new study, researchers Kieron Barclay and Martin Kolk try to detangle the physiological and social explanations for this relationship.   [...]
In a recent paper, researchers Zachary Van Winkle and Emanuela Struffolino addressed the issue of in-work poverty – an alarming phenomenon which is exceptionally common in the United States. They considered life courses of individuals from age 18-50 who were born between 1957 and 1964 in the United States, and particularly focused on the association between family demographic processes and the probability of belonging to the working poor. [...]
Often fertility rates are analysed at the country level. However, it is also often disregarded that there are economic, political and cultural regional differences within a country, which have a considerable influence on the respective opportunity structure of women and families. In a recent article, Martin Bujard and Melanie Scheller examine cohort fertility rates for all German districts. They provide a broad overview of factors influencing birth behaviours at a local level and to what extent these factors can explain regional differences. [...]
When speaking about attitudes towards immigration, one argument is often used: Individuals who compete with immigrants in the labour market are said to be more against immigration than individuals who do not. Empirical support for this argument is widely debated, but still it remains. [...]
Can social media channels like Facebook be used to analyse fertility data? According to recent research, it can be. In a paper by Francesco Rampazzo, Emilio Zagheni, Ingmar Weber, Maria Rita Testa and Francesco Billari, they sought out to determine if anonymous and aggregate data from Facebook advertising can be a viable source for fertility data. This is particularly relevant when looking at developing countries, where official data is less available. [...]
Decades of social science research provide plenty of evidence on ethnic and racial discrimination in various areas of society based on ethnographic work and analysis of traditional data sources. Online markets offer a new perspective to study the diverse settings in which ethnic discrimination can occur and provide new channels to test assumptions about why and how members of ethnic or racial groups are being discriminated against. [...]
Inequalities in health are not only caused by biological determinants, but also by social determinants like income or education. One’s own socio-economic position has been shown to often be an important predictor for health and mortality. A recently published article by Jenny Torssander, Heta Moustgaard, Riina Peltonen, Fanny Kilpi and Pekka Martikainen sheds further light on the assumption that not only someone’s own resources affect health and mortality, but the resources of the partner one lives with also play a role.
