POPJUS researchers have been honored with the IPUMS International Research Award, recognizing outstanding research using IPUMS data!

The Integrated Public Use Microdata Series (IPUMS) Research Awards honor outstanding research using IPUMS data to advance or deepen our understanding of social and demographic processes.

In the published paper Drought and Aridity Influence Internal Migration Worldwide, Roman Hoffman, Guy Abel and Raya Muttarak adopt a novel approach to analyzing how drought and aridity shape internal migration patterns across sub-national regions, age groups, and education levels. Their findings reveal that climate change has a significant impact on internal migration, with the strongest effects observed in arid and hyper-arid areas. Using 72 IPUMS International census samples and climate data, they analyze over 100,000 migration flows. The study makes strong use of spatial harmonization, sub-national geography, and migration variables, showcasing the depth of IPUMS data. Enhanced by detailed maps and visualizations, the paper offers valuable comparative insights into climate-related migration.

We congratulate them on this excellent achievement.

The world’s wealthiest 10% caused two thirds of global warming since 1990

Wealthy individuals have a higher carbon footprint. A new study published in Nature Climate Change quantifies the climate outcomes of these inequalities. It finds that the world’s wealthiest 10% are responsible for two thirds of observed global warming since 1990 and the resulting increases in climate extremes such as heatwaves and droughts.
