At the 2016 census, 649,171 people (2.8% of the total population) identified as being Indigenous — Aboriginal Australians and Torres Strait Islanders. Indigenous Australians experience higher than average rates of imprisonment and unemployment, lower levels of education, and life expectancies for males and females that are, respectively, 11 and 17 years lower than those of non-indigenous Australians. Some remote Indigenous communities have been described as having "failed state"-like conditions.
