Extended family networks are changing. This has implications for us all.

Do you have fewer cousins than your parents did? This is not a coincidence, but part of a broad global trend. Families are getting smaller all around the world and their composition is changing rapidly. Diego Alburez-Gutierrez, Iván Williams, and Hal Caswell outline these processes in a new paper and discuss their implications for societies.

Diego Alburez-Gutierrez, Iván Williams, and Hal Caswell's new paper projects the evolution of human kinship relationships worldwide. It shows the broad global trend that families are getting smaller and that their composition is changing rapidly.

Beyond Overestimation: Refining Migrant Data for a True Picture in Sweden

This study examines to what extent international migrants were overcounted in population data in Sweden from 2003 to 2016. It finds that, in general, overcounting was relatively low in this period. However, there are discrepancies across socio-demographic groups.

Healthy Immigrants, Unhealthy Ageing?

Every year, millions of people decide to leave their homes and move to Europe for many and varied reasons. But what happens to their health after the migration as they grow old in another country? Su Yeon Jang, together with Anna Oksuzyan, Mikko Myrskylä, Frank van Lenthe and Silvia Loi, explored this question in their latest paper.

Complex migrant journeys depend on four factors: knowledge, networks, life situation – and chance

Migrant journeys are complex and can be unpredictable. Migration routes can change, sometimes rapidly. This creates challenges for policy and for computer simulations of migrant routes. Researchers have identified four crucial factors for migration modelling – and they caution against oversimplifying reality.

Lowered minimum legal drinking age associated with increased alcohol-attributable morbidity and mortality decades later

In their cohort study published in the Lancet Public Health, Juha Luukkonen et al. assessed whether being legally able to purchase alcohol at younger age was associated with later alcohol-attributable morbidity and mortality.
