The Index of Manufactured Exports (IME) was a quarterly publication measuring growth, in real terms, of overseas export sales by the manufacturing sector in Scotland. From 2016 Q3 (published in February 2017), IME has been incorporated into Quarterly National Accounts.
Estimates of Scottish manufactured exports are compiled on the standard industrial classification UKSIC (2007). The estimates are derived from data on sales of goods produced by the Scottish manufacturing industry for export outwith the UK. The Office for National Statistics (ONS) collects the data used to produce these figures in their Monthly Business Survey. Export estimates for the refined petroleum products industry are calculated using a volume series supplied by the Department for Energy and Climate Change (DECC) and informed by data from the UK Energy Trends. Exports sales of the companies covered by the survey are grossed up to represent the entire population using the Inter Departmental Business Register (IDBR).
The data are deflated using UK export producer price indices produced by the ONS, and seasonally adjusted where appropriate, to produce an estimate of growth in volume terms. Annual export values from the Scottish Government's latest Input-Ouput tables and Global Connection Survey provide benchmarks and annual chainlinking weights for the quarterly IME estimates. The final results are presented in Chained Volume Index form at constant 2013 prices.
The index of Scottish manufactured exports is based on a sample of around 800 Scottish manufacturing companies per quarter. This sample covers all sizes of unit across the manufacturing sector.
