Where possible, weighted prevalence estimates were obtained from the ABS, which weights samples by jurisdiction of residence, age, sex, and level of remoteness, to produce estimates that represent the Australian population. The ABS did not categorise National Health Survey participants into European or Asian ancestry, and consequently, weighted estimates were not available for these two populations. Instead, unweighted prevalence estimates for participants of European or Asian ancestry were derived in the ABS DataLab. Communality estimates were obtained from the ABS DataLab for participants aged 45 years and older. Communality estimates for all Australians were used for people of European and Asian ancestry.

ABS=Australian Bureau of Statistics. *Communality estimates for First Nations Australians were based on 1779 participants who had complete data for all risk factors in the ABS DataLab. †Social isolation prevalence estimates were obtained from the ABS General Social Survey (2014) via TableBuilder for all Australians, and people of European and Asian ancestry. Communality estimates for social isolation were the average of all other communality estimates for all Australians. ‡Social isolation prevalence estimates were obtained from the ABS National Aboriginal and Torres Strait Islander Social Survey (2014–15) via TableBuilder for First Nations Australians. Communality estimates for social isolation were the average of all other communality estimates for First Nations Australians.
