What is Demography?

© mathias the dread, Koosinger, suze / photocase.com

Demography is the science of populations. Demographers seek to understand population dynamics by investigating three main demographic processes: birth, migration, and aging (including death). All three of these processes contribute to changes in populations, including how people inhabit the earth, form nations and societies, and develop culture. While most of the discipline’s research focuses on humans, the MPIDR is also committed to the specialized field of biodemography.

Today, there is growing interest among the public in demography, as “demographic change” has become the subject of political debates in many developed countries. Most of these countries have birth rates below the replacement level of 2.1 children per woman, and, at the same time, life expectancy has been rising considerably and continues to rise – a development sometimes called “the aging of societies.”

While demography cannot offer political advice on how to tackle demographic change, demographers seek to describe the phenomena related to this change, and to understand their causes. Using reliable data and the statistical processing of these data, modern demographic research embraces many scientific disciplines, including mathematics, economics and other social sciences, geography or biology.

Selected MPIDR research for the public

The following articles and digests cover actual demographic topics, or provide an overview of the Institute’s research fields, and their meaning for society. The media and the public can also access a selection of MPIDR’s research at the Institute’s press release archive and news archive. More comprehensive articles can be found in the publications section.

Information for students and teachers

Educational film

For secondary school students (grades 9-12), the MPIDR and the Max Planck Society have prepared extensive teaching materials under the heading “Bevölkerungsentwicklung in Deutschland.” These materials are available to teachers at FWU – Das Medieninstitut der Länder, and include an educational film intended to serve as an introduction to the field of demography. (Materials are available in German only)

Special GEOMAX demography issues

Download one of the digest issues “Reisen in der Zeitmaschine – womit Demografen in Zukunftrechnen müssen” (PDF, 206 kB) or “Sieht Deutschland bald alt aus? – dem demografischen Wandel auf der Spur” (PDF, 837 kB)  (both in German) from the popular science serial “GEO MAX – Neugierig auf Wissenschaft,” published by the Max Planck Society. www.max-wissen.de

Wissenskarawane

Once a year, the MPIDR opens its doors to about a hundred students from schools in the Rostock area, introducing them to the world of demography, and showing them how demography is being studied at the MPIDR. Groups of students tour the Institute, visit its labs, and learn about birth, death, and their own lives. The event is suitable for secondary school students in grades 10 and 11. www.wissenskarawane-mv.de
