The conference was held in a hybrid format.

Posters, presentations and abtracts can be found below.


Understanding and analyzing population heterogeneity and its drivers have long been at the heart of demographic analysis. For instance, while inequalities in health and life expectancy across socio-economic groups have been studied since long, their increase over the past decade has turned into a growing concern. In addition to “classical” markers of heterogeneity in individual behavior, such as sex/gender, age, education, urban-rural residence and socio-economic status, there are other important sources of demographic heterogeneity such as spatial, generational, environmental, etc. Their analysis is essential for modeling population developments and projecting them into the future. Equally important is to understand how these heterogeneities arise and evolve, how they are driving and driven by socioeconomic inequality, and the policy challenges they impose for socio-economic development, welfare systems and social cohesion.

From 6 to 7 December 2023 the Wittgenstein Centre Conference on “Exploring Population Heterogeneities” took place at the premises of the Austrian Academy of Sciences. The interest in the hybrid WIC2023 Conference was high, and participation lively and international. We received 272 submissions in total and 423 registrations from 66 countries overall. 128 participants from 26 countries took part on-site. We were delighted to follow the keynote lectures held by Ridhi Kashyap, Anna Matysiak and Iñaki Permanyer as well as 25 talks, 9 flash talks and 27 poster presentations. Please find impressions,  the schedule, abstracts, posters, slides and videos of talks below.
