Rapid Demographic Changes Reshape Family Structures

Declining birth rates and rising life expectancy are reshaping the size and age structure of families worldwide. A recent study reveals that the question is not only whether these changes will occur, but also how quickly they will unfold. Analyses of real population data from Thailand, Indonesia, Ghana and Nigeria as well as stylized scenarios confirm this trend. In countries undergoing rapid demographic change, people with an age difference of only five to ten years may have drastically different kinship networks.  More

Should you Claim Your Pension Early or Wait?

In the US, the later you retire, the higher your monthly pension benefit will be. Researchers have investigated whether this is optimal, given the uncertainties surrounding life expectancy. The results show that delaying retirement poses a particular financial risk to men and low-income groups, and that different decisions are necessary depending on individual circumstances and uncertainty.  More

How can we Link NBA Basketball, Physics, and Demography?

Can we predict Steph Curry’s next move on the court?
Last year, Boris Barron started at MPIDR as a research scientist in the Migration and Mobility Department. He is a physicist and specializes in modeling complex systems. While at Cornell University, he and his colleagues developed a methodology to analyze detailed positional information of basketball players in NBA games. Their approach adapted a physics-based approach, Density Functional Fluctuation Theory (DFFT), to provide a general framework to infer subtle aspects of the game.  More
