In the SHS collection, older persons are generally those aged 55 and over and  older and Aboriginal and Torres Strait Islander people are aged 50 years and over. In the longitudinal analysis section of the report, any client who used services between 2013–14 and 2017–18 and is 55 or older on 30 June 2018 were included. Therefore, some clients included may have been under 55 when they had their first or only support period prior to the 30 June 2018 cut-off.
