As part of its work to produce the Q1 2019 Quarterly Construction Enquiry (QCE) publication, which was published on 18th July 2019, NISRA identified an error that affects the data presented in the 2018 Q1 to Q4 publications previously released. Importantly, the extent of the error does not amend the overall direction of the trend of the NI Construction sector that was presented in these previous releases.
Tables containing corrected figures for the four quarters in question were issued on 18th July 2019 alongside the Q1 2019 QCE publication, which include further details on the nature and impact of the error. The corrected figures were incorporated in the Northern Ireland Composite Economic Index, which was also published on 18th July 2019.
NISRA will review its processes to minimise the risk of such errors occurring in the future and apologises for any inconvenience caused.
In line with best practice, a wider methodological review of the NI QCE is planned to be undertaken over the next number of months. A full update on the methodological assessment will be published alongside any revisions that may occur as a result of the review.
