Newcastle and Hunter Valley 21st century population graphs
I thought these might be useful for people discussing growth, congestion and other population-related topics. This is simply a time series visualisation of the ABS Estimated Resident Population data for 2001-2023.
Population is segmented by Statistical Area Level 3 (SA3) within the SA4 areas 'Newcastle and Lake Macquarie' and 'Hunter Valley exc Newcastle', and broken down to SA2 areas in the later slides, which are useful for seeing exactly where growth has been happening. You can explore these areas and more on maps.abs.gov.au.
The region has grown roughly 28% this century (550,532 + 156,475 = 707,007 residents), but that growth has been unevenly distributed and largely peripheral to the metropolitan area. Maitland, for instance, added 3400 more residents than Newcastle. In context, Blacktown and Parramatta added roughly the same number of residents, but their rate of growth was much higher (62% and 48%).
People's perception of growth is likely heavily influenced by their home and work locations. Broadmeadow grew 5.5% from 2015 to 2023; Fletcher grew 28%. Who is likely to perceive more growth and greater congestion?
