The Northern Ireland Composite Economic Index (NICEI) is an experimental quarterly measure of the performance of the Northern Ireland (NI) economy based on available official statistics. It is not possible to provide a comprehensive measure of quarterly Gross Domestic Product for NI due to the lack of suitable data sources. Comparisons with UK GDP measures are therefore approximate. However, the NICEI provides an appropriate short term indicator for the NI economy in advance of more complete figures from other sources such as annual Regional Accounts information for NI from ONS.
This report was initially planned for publication on the 17th December 2014. However, quality assurance of final estimates for the Index of Services (IOS), which is a key input data source, identified the need for additional checks. This was due to the increase in the IOS sample size which highlighted a number of potential differences between the old and new series at sector level, which required further investigation.
