The ABS’s regional population figures released today confirm Queensland is second only to WA in population growth, and that the Brisbane metro area’s population growth is concentrated in the Western Corridor through Ipswich and West Moreton. The ABS has also uncovered this elegant and striking fact about the population centre of Brisbane (which is a demographic concept akin to a centre of gravity):
The centre of population for Brisbane SD [Statistical Division] at June 2010 was in the Botanic Gardens on the banks of the Brisbane River, just south of the city’s central business district.
So Brisbane, it appears, is still a reasonably balanced city without the uncontrolled urban sprawl of say Sydney, where the population centre is near Parramatta, or Melbourne, where it is in Glen Iris, 10km south-east of the city.
If Brisbane is to maintain this balance, we’ll need to continue to increase population densities in our inner city and surrounding suburbs such as Coorparoo and Indooroopilly, while ensuring that the development of outer suburbs occurs in an orderly fashion.
Incidentally, the population centre of Queensland also lies in a pleasant spot:
Queensland’s centre of population at June 2010 was in the LGA of North Burnett (R), roughly 100 kilometres west of Maryborough. The centre moved approximately 1.7 kilometres east-north-east in the five years to June 2010, reflecting sustained population growth in Queensland’s coastal regions over this time.
