Marton Karsai, "Socioeconomic correlations in social and mobility networks and their change due to external shocks"


Socioeconomic segregation patterns in networks usually evolve gradually, yet they can change abruptly in response to external shocks. The recent COVID-19 pandemic and the subsequent government policies induced several such interruptions in societies, while their digital observations opened up a natural laboratory to study their effects. Here we address how lockdown interventions lead to the reorganization of socioeconomic segregation. We demonstrate that not all social groups could adapt equally to the emergency situation, suggesting socioeconomic status as an important determinant of people’s capacity to reflect to global emergencies. Our study find opposite reorganization patterns of segregation following different behavioral traits of the same people and highlight how emergency policies may induce unequal burden, potentially disadvantaging vulnerable communities.
