Release notes

Trend series reinstated in September quarter 2022

Review of trend suspension

In early 2020 the ABS suspended the trend series, in addition to adopting forward factors to produce seasonally adjusted series. The trend estimate indicates the medium to long-term direction of a time series. To estimate the trend, the effects of significant events like disruptions associated with COVID-19 are assigned to either the trend or irregular components of a time series. The rationale for suspending trend series was that it was unknown whether the impacts from COVID-19 would be short or medium to long-term, and therefore there was high probability of needing to significantly revise initial assessments of the impacts of COVID-19 on the trend.

The trend series for Mineral and Petroleum Exploration has been reviewed and reinstated.

Over the last two years, the impacts of COVID-19 on Mineral and Petroleum Exploration series have not caused multiple abrupt changes in the series level in short succession, and so it is appropriate to describe a trend level through the past two years. As a result, Mineral and Petroleum Exploration will also be publishing a trend over the previous two years for relevant series.
