A correction has been made to the Business investment time series dataset. This is due to an error being identified when comparing the data published in the Business investment by industry and asset breakdown.
These estimates have been improved since the ad hoc series published after Blue Book 2013. The improvements have meant that the series, which were suppressed in the ad hoc release, have now been reinstated. However, there are still differences between the business investment chained volume measure seasonally adjusted estimates in this dataset and the official estimates published in the Business investment release. These differences are due to the different seasonal adjustment approaches. In this dataset, industry-level series are seasonally adjusted and aggregated. In the Business investment release, the asset-level series are seasonally adjusted and aggregated. This can give different results for the aggregated series. The estimates in the Business investment release should be considered the official statistics.
Please note that not all series will sum to totals due to rounding. These differences are well within the uncertainty of the estimates.
The breakdowns will next be updated in line with the revised Quarter 4 (October to December) 2017 results. The updated time series dataset will be released on 22 February 2018.
