Jakub Bijak

Jakub Bijak is Professor of Statistical Demography at the University of Southampton's Department of Social Statistics and Demography, with nearly 25 years of academic and international civil service experience. He actively contributes to the Statistical Sciences Research Institute (S3RI) and Centre for Population Change, leading research at the intersection of demographic theory, statistical methodology, and policy application. His work bridges demographic science with practical migration governance challenges across European institutions.

He earned his PhD in economics with specialisation in demography from the Warsaw School of Economics, establishing his foundation in quantitative demographic analysis. His doctoral research directly informs his ongoing focus on methodological innovation in population studies.

Professor Bijak's research centers on statistical demography, migration modeling under uncertainty, and demographic forecasting. He pioneers agent-based simulation approaches for migration decision-making and develops Bayesian frameworks for population projection. His work spans from paleodemographic analysis of ancient populations to contemporary migration governance, with particular emphasis on quantifying uncertainty in demographic processes. Recent projects explore digital trace data for real-time migration monitoring and kinship dynamics across the life course.

Analysis of his 2024-2025 publications reveals three dominant trends: (1) Methodological innovation in migration forecasting using mixed-frequency data and agent-based modeling, (2) Integration of digital footprint analysis for timely migration estimates, and (3) Development of policy-relevant frameworks for managing demographic uncertainty. His work increasingly connects demographic modeling with robotics and aging populations, demonstrating cross-disciplinary impact.

Professor Bijak currently supervises two PhD students: Andrew Peter Hind (MPhil/PhD Social Statistics) and Md Sifat Ar Salan (PhD Social Statistics and Demography). He leads or co-leads multiple major research projects including QuantMig (European Union-funded), Bayesian Agent-based Population Studies (BAPS), and ESRC/EPSRC grants on population change. His projects frequently involve international consortia addressing migration scenarios, demographic uncertainty, and generational connections.

He maintains active roles in the Statistical Sciences Research Institute and Centre for Population Change, contributing to interdisciplinary teams developing the QuantMig microsimulation platform and kinship modeling frameworks. His collaborative networks span demography, computer science, and policy institutions across Europe.
