Australian Bureau of Statistics estimated that 4.35 million people lived in Greater Melbourne in 2013. Melbourne's population is projected to increase continuously to between 7.6 and 9.8 million in 2061, becoming the nation's largest city. Rapid population growth creates a great challenge for urban planners and policy makers dealing with demand and supply pressures on energy, water, transport, land, and the environment.
In this project, we present a series of interactive visualizations showing how demographics of Melbourne have changed over time using Census data. This project is inspired by the "Washington DC: Our Changing City" developed by the Urban Institute.
The first series focus on population growth. Two main components of population growth in Australia is natural increase and net overseas migration. Natural increase is the number of deaths subtracted from the number of births. Net overseas migration (NOM) is the difference between permanent and long-term arrivals, and permanent and long-term departures. The motion bubble chart on the right shows how these two major components have changed and contributed to population growth in different Australian states over years.
This project is funded by the Faculty of Engineering Seed Funding and the Immersive Analytics Project at Monash University.
