Professor Jakub Bijak is joint Head of Department of Social Statistics and Demography Professor of Statistical Demography at the University of Southampton.

My research interests focus on the methods for dealing with the uncertainty of demographic phenomena, in particular surrounding migration and the demography of armed conflict.

I joined Social Sciences, University of Southampton in February 2009. Between 2003 and 2008, I was a researcher in the Central European Forum for Migration and Population Research (CEFMR) in Warsaw. In the period 2001–2003, I worked in the Demographic Unit of the UN International Criminal Tribunal for the former Yugoslavia (UN ICTY) in the Hague, analysing population consequences of the 1990s armed conflicts in the Balkans.

I hold PhD in economics (with specialisation in demography) and an MSc Quantitative Methods and Information Systems, both obtained from the Warsaw School of Economics.

I have received the Allianz European Demographer Award (2015), conferred by Allianz SE, the Berlin Demography Forum, and Population Europe for “outstanding research on the causes and consequences of population developments in Europe”. An interview following the award ceremony can be watched via Population Europe Inter-Faces on YouTube. I have also been awarded the Jerzy Z. Holzer medal of the Committee of Demographic Sciences, Polish Academy of Sciences (2007), for contributions to the Polish demography.

Professional activities

Research interests

My research interests focus on the applications of quantitative methods in demography, especially in migration and population forecasting, agent-based population modelling, demography of conflict and violence and international migration studies, as well as on research on population ageing, mortality, links between population and the environment and demographic uncertainty. In particular, I am interested in the methods of mathematical statistics, especially in the Bayesian approach, including econometric modelling, stochastic processes and decision-making under uncertainty.

I currently lead a project on Bayesian Agent-Based Population Studies, funded by a Consolidator Grant of the European Research Council, and am also a co-leader of the modelling strand of the ESRC Centre for Population Change.

Research projects:

ESRC Centre for Population Change (CPC) strand on "modelling population growth and enhancing the evidence base for policy" (2009-2013, 2nd edition 2014-2018)

EPSRC Care Life Cycle (2010-2015)

ESRC Future of Scotland Project, an additional activity of the Centre for Population Change (2013-2014)

Integrated Modelling of International Migration (2009-2012)

Bayesian forecasting of immigration into European countries

How does natural and anthropogenic disturbance change human population growth? (2014-2017)

Working Papers

In the winter semester of 2018-19, I will be contributing to Demographic Methods I (DEMO6020) and Philosophy of Social Science Research (RESM6001). In the summer semester, I will be teaching Demographic Methods 2 (DEMO6022) and contributing to Time Series Analysis (STAT6087).
