Permalite, Australia has 18M people back then. 18M v 323M. It's common sense that it's nowhere near the same. Australia is massive landwise but the majority of people are concentrated in the capital cities or around them.
Of course, that's why we have this wonderful statistic called homicide rate, which takes in account population:
The US has 4.88/100 000 people, versus 0.98 in australia (and similar numbers in other fully devellopped nations.)
For its development, there is no question that the US is an outlier, in its violence.
