Sigurd Dyrting

Sigurd Dyrting is a Researcher at the Northern Institute, part of the Faculty of Arts and Society at Charles Darwin University. He specializes in demographic analysis with a focus on small population estimation techniques and population projections for the Northern Territory of Australia. His work contributes to UN Sustainable Development Goals related to sustainable communities and reduced inequalities.

His educational background includes a Bachelor's degree from the Australian National University and a PhD in Quantum Chaos in Atom Optics from the University of Queensland. This unique combination of physics and demographic expertise informs his methodological approach to demographic problems.

Dyrting's research interests center on applying mathematical, statistical, and computational methods to demographic problems, particularly estimation techniques for small populations. His work emphasizes preparing inputs used by practitioners for demographic analysis and population projections. He has developed expertise in smoothing techniques like P-TOPALS for migration and mortality data, and has contributed to understanding internal migration patterns, population shrinking in the Northern Territory, and social capital measurement.

His recent publications (2019-2025) show a strong focus on Northern Territory demographic challenges, with particular attention to migration flows, population projections, and methods for small area estimation. The research demonstrates a progression from theoretical demographic methods to applied policy-relevant studies addressing specific Territory challenges.

Dyrting currently leads or collaborates on significant research projects including the Northern Territory Department of Health Population Estimates by Regions (2024-2025) and the Northern Territory Department of Treasury and Finance Demographic Research Grant (2024-2026). These projects address critical demographic challenges facing the Territory.

He is registered to supervise postgraduate research and has been involved in multiple collaborative projects addressing Northern Territory demographic issues. His research has received media attention, particularly regarding population trends during the COVID-19 pandemic and strategies to address population shrinking in the Territory.
