A team of researchers from the Laboratory of Digital and Computational Demography at the MPIDR produced a database that contains the number of academics per country, and the migration flows and rates from 1996 to 2021. They also analyzed the relationship between emigration and economic development per country. Their findings indicate that the patterns for the migration of academics may be widely different from the population-level ones, not necessarily leading to brain-drain. more

The world of a couple changes fundamentally after childbirth. Whether the partners are as satisfied with their relationship then as they were during their childless phase hinges in part on how fair they perceive the division of labor to be.

Researchers of the Digital and Computational Demography Lab at the Max Planck Institute for Demographic Research (MPIDR) and colleagues recently published a paper in the “Journal of the Royal Statistical Society: Series A” which systematically assesses the quality of Facebook’s ads data for use in social science research. They assessed the accuracy of this data by comparing self-reported and Facebook-classified demographic information on sex, age and region of residence of more than 133,000 users recruited via an online survey. Their results suggest that Facebook’s ads data can be used when additional steps are taken to validate the accuracy of the information under consideration.  more

A historical comparison of data, however, offers hope for rapid improvement. Those are the findings of a new study by MPIDR Researcher Jonas Schöley and his colleagues at Oxford University's Leverhulme Centre for Demographic Science that examined changes in life expectancy in 29 countries, published in the journal “Nature Human Behaviour”. more
