4.1 The “Enhancing Australia's CPI” program has provided an opportunity for the ABS to re-examine the frequency of updates to the CPI and SLCIs expenditure weights.
4.2 The ABS has conducted detailed investigations into increasing the frequency of EC weights updates by using HFCE data in the inter-HES years for both the CPI and SLCIs. These investigations address the various challenges in using HFCE data for these purposes.
4.3 The ABS has now completed further investigations, and provided empirical results that support the annual re-weight of the CPI and SLCIs in the inter-HES years using HFCE.
4.4 The ABS will update the Australian CPI and SLCIs expenditure weights using HFCE data in the inter-HES years, starting December quarter 2018.
