IOS results for Q2 2013
Northern Ireland Index of Services (IOS)
The experimental Index of Services (IOS) was first published in Northern Ireland on 18 May 2005. Following assessment by the UK Statistics Authority the Index of Services was designated as a National Statistics on 5 August 2011. It is published quarterly and is designed to provide a general measure of changes in the output of the private sector service industries in Northern Ireland. (This is defined as Standard Industrial Classification 2007 (SIC07) sections G to S. In 2008 these private sector service industries accounted for 64% of regional Gross Value Added (GVA).
The quarterly NI IOS Statistics Bulletin presents the latest seasonally adjusted estimates from the NI Index of Services including comparison with published figures for the UK as a whole.
The IOS sample was refreshed for Q2 2011 and was drawn on a SIC07 basis. It is now approximately 20% larger with approximately 1,900 companies. Due, in part, to the significant number of companies which fall into the census element, approximately 50% of businesses in the new sample were also in the old sample. As a statutory survey the response rate is now over 80%. The sample of service industries is selected directly from the Inter Departmental Business Register (IDBR), by stratifying companies by industry and company size. The sample consists of a census of dominant companies and a Neyman stratified random sample of the remaining companies. The census element consists of all companies employing 100 or more employees and those employing 0 to 99 employees and having a turnover of £20 million or more. It is desirable to include these low employment high turnover companies in the sample in order to provide a more comprehensive picture of the overall economy.
It is based on up-to-date information about the output and sales of the services industry. The index is published in January, April, July and October each year and refers to the quarter ending some 15 weeks earlier.
All series, unless otherwise quoted, are measured at constant market price (2010 = 100). Deflators adjust the value series to take out the effect of price change to give the volume series. Details on the changes to the ONS deflators methodology can be found at the following link http://www.ons.gov.uk/ons/guide-method/method-quality/specific/economy/national-accounts/articles/deflation-improvements-in-the-uk-national-accounts.pdf
