In the last 50 years there has been a substantial increase in the proportion of Australians living alone.
In 1961, just over 1 in 10 Australian households (11%) had only one resident. In 2012–13, lone-person
households increased to almost 1 in 4 (23%) (ABS 2015). An estimated 2.1 million people currently live
alone in Australia (ABS 2015).
