Through its research, the MDM Group aims to advance demographic modeling methods to assess and forecast population dynamics with a focus on demographic and spatial heterogeneity under different socioeconomic scenarios at the global, national, and sub-national level.

The MDM Group’s research focus is at the core of the IIASA strategic plan in rigorously incorporating the human-centered system model into systems analysis by considering the feedback mechanisms between human and other social, economic, and natural systems. The group has a strong focus on population forecasting using a scenario-based approach allowing for aligning future demographic components with socioeconomic scenarios such as the Shared Socioeconomic Pathways (SSPs) originally developed for the climate change research community. Apart from updating global projections of population, human capital, and other relevant dimensions using scenarios, the group also carries out innovative, policy-relevant research at the local and regional level, for instance, assessing social vulnerability to COVID-19 at a small spatial scale.

Latest European Demographic Data Sheet highlights lasting impact of war and migration

The Russian invasion of Ukraine and the consequent displacement of millions of people will have a significant impact on the country’s long-term population structure. Researchers from the Austrian Academy of Sciences, IIASA, and the University of Vienna are forecasting a substantial population decline of 21-31% by 2052.

Populations of the future: updated tool helps to visualize projections

New projections of population and human capital provide insights into what our future could look like all the way until the year 2100 under different developmental scenarios. The findings are presented in datasets compiled by IIASA scientists in partnership with the Wittgenstein Centre for Demography and Global Human Capital.

Predicting EU migration trends: merging traditional and social media data

IIASA researchers Dilek Yildiz and Guy Abel highlight the benefits of a new statistical model that combines traditional data sources like the census with real-time Facebook data to estimate EU migrant populations, offering valuable insights for policymakers.

Human capital growth persists with upcoming population decline

The world's population has surged from 1 billion in 1800 to just above 8 billion today, but demographers predict this growth will halt by the end of the 21st century. IIASA researcher Guillaume Marois explains how a new human capital-weighted population metric is reshaping our understanding of global population dynamics and economic potential.
