This paper reports investigations into the feedback and linkages between demographic change and infrastructure provision. In this paper, we seek to explore the coupled dynamic of demographics, the economy and infrastructure simultaneously as a series of subsystems. The modelling results will explore different policy scenarios for regional infrastructure investment to offer an initial proof of concept of the feasibility of implementing a coupled model of demographic and economic growth over a medium to long time horizon, and promises a distinct and exciting perspective on the co-dynamic interplay of social and economic policies, regional development, infrastructure provision and prosperity.
