The Interdisciplinary Centre on Population Dynamics (CPop) is a cross-faculty collaboration between researchers drawn from demography, public health, biology, mathematics, economics, political science and humanities . The center conducts innovative research to discover the basic causes and key consequences of changes in survival, longevity, and population aging, including also their policy implications.
The consequences of aging are of utmost importance to society. Understanding of and capability to address the challenges posed by longer, healthier lives require insightful, cross-disciplinary research. CPop therefore build on the success of MaxO and expand from its focus on biodemography into a unique four-faculty virtual institute with scholars from four faculties of SDU. The center bridges research in biological demography (Biology department) with epidemography at the health sciences (Department for Epidemiology, Biostatistics and Biodemography) using a solid foundation of mathematical and computational methods (Department of Mathematics and Computer Science). Further, it complements its studies on survival and longevity by research on the consequences for public health (Department of Business and Economics), on the interplay between demographics, politics and policies (Danish Centre for Welfare Studies) and research in the new cultures of ageing in the literary studies (Department for the Study of Culture).

The urbanization penalty, new research draws lessons about the impact of urbanization on mortality from the past
Urbanization, closely linked to industrialization, has been progressing unevenly across time and space around the globe for more than two centuries. The early stages of urbanization have had often one thing in common and that is its uncontrolled organic growth with negative consequences for health and environment. According to WHO, many developing cities today are “focal points for many emerging environment and health hazards”. In their new paper Catalina Torres and co-authors look back to the beginnings of urbanization in Scotland and quantify the penalty of urbanization. They quantify not only the direct toll paid by urban inhabitants exposed directly to the unsanitary and hazardous environment in the form of higher mortality, but they also quantify the effects of changing population redistribution on total life expectancy of Scotland between 1861 and 1910. In other words, they are able to isolate direct and structural effects of urbanization on mortality and survival in Scotland. The capacity to disentangle these two effects is useful when studying current urbanization hazards and its consequences in developing countries.

Upsurge in homicides decreases life expectancy and life span equality among males in Mexico according to new demographic research
A new study published in a leading journal of public health shows that the recent increase of homicides in Mexico negatively impacted life expectancy for males and increased their lifespan inequality. The upsurge of homicides is related to the Mexican government’s effort to mitigate drug cartel activities that initiated a cycle of violence – so-called War on Drugs since 2007. The study shows that in the period between 2005 and 2015 homicides were the main cause of death for young males aged 15 to 50 years, and increased more than 50% in this period, from 20.4 to 31.2 per 100,000. Homicides largely acted against improvements in other health outcomes caused by public health interventions. Similar negative effects of violence can be expected in other countries of the region such as El Salvador, Honduras and Venezuela where homicide levels are even higher. Mexico needs to recognize and correct the detrimental consequences in health and human rights that suppressive and drug-prohibition policies have had on the population. Rather than military action against drug cartels the government should re-focus on improving social and human capital through education, community support and employment programs.

Iain Stott has been awarded €200,194.80 by the European Commission for the Marie Słodowska-Curie Actions Standard Fellowship WHYAGE, to be conducted at MaxO (now DEM), SDU in collaboration with the University of Zurich. The WHYAGE project will use global demographic datasets developed by MaxO and other institutions, alongside novel theoretical models, to explore feedbacks between age-patterns of survival and fecundity, and population dynamics.

New project: Efficient survey and response to invasive species using drones. This is a joint project of Johan Dahlgren (DEM), Owen Jones (DEM) and Henrik Skov Midtiby at the UAS Center, SDU Faculty of Engineering. It is funded by the University of Southern Denmark, as part of an initiative to fund outreach projects using drones. We will use “unmanned aerial vehicles”, UAVs, to monitor populations of problem species of plants.

Our paper "Better the devil you know: common terns stay with a familiar partner although pair duration does not affect breeding output" by Rebke, M., P.H. Becker and F. Colchero (2017) was published in Proceedings of the Royal Society B 284:2016.1424
We developed a Bayesian hierarchical model to analize the survival, breeding success and partner choice in a colony of common terns. We tested whether individuals choose a partner based on their previous breeding success or based on their familiarity. We found that partner choice was determined by the number of breeding times the pair had mated, and not based on previous breeding success.

Public interest in social and economic equality is burgeoning. We examine a related phenomenon, lifespan equality, using data from charismatic primate populations and diverse human populations. We found that lifespan equality rises in lockstep with life expectancy, across primate species separated by millions of years of evolution and over hundreds of years of human social progress. Furthermore, we show that, in these measures, industrial humans differ more from nonindustrial humans than nonindustrial humans do from other primates. Finally, in spite of the astonishing progress humans have made in lengthening the lifespan, a male disadvantage in lifespan measures has remained substantial—a result that will resonate with enduring public interest in male–female differences in many facets of life.
