SCOTTISH MANUFACTURED EXPORTS FOR THE SECOND QUARTER OF 2007

A Scottish Government National Statistics Publication

Scottish manufactured export sales increased by 4.4 per cent in real terms in 2007 Q2 and grew by 3.6 per cent over the year to 2007 Q2, according to estimates published today by the Scottish Government.

The main findings are:

Scottish manufactured export sales increased by 4.4 per cent in real terms in 2007 Q2 and grew by 3.6 per cent over the year to 2007 Q2.

Over the quarter, the main industry driving the increase in manufactured export sales was engineering which grew by 12.9 per cent over the latest quarter followed by metals & metal products (+8.0%) and chemicals & refined petroleum (+2.6%). The main industries showing decline in real terms were drink (-9.3%), wood, paper & publishing (-7.0%) and food & tobacco (-6.3%).

Over the year, engineering and drink were the main industries contributing to the growth in manufactured export sales with annual growths of 6.2 per cent and 3.4 per cent respectively. Metals & metal products also showed strong growth over the year (19.0%). The main industry showing a decline in manufactured export sales in real terms over the year was chemicals, with an annual decline of 3.3 per cent. Food (-6.2%), wood, paper, publishing & printing (-6.5%) and other manufacturing (-4.3%) also fell over the year.

Longer Term Trends

Over 1995 Q1 to 2000 Q4, the index of manufactured exports exhibited a period of strong growth (1.9% average quarterly growth) which was followed by a sustained period of decline from 2000 Q4 (3.6% average quarterly decline 2000Q4-2003Q3). Since the end of 2004, there has been evidence of modest growth in manufactured export sales.

The growth and decline in manufactured exports over the period 1995-2004 is largely explained by the electrical and instrument engineering sector which grew by 124.6 per cent between 1995 Q1 and 2000 Q4 and fell by 65.9 per cent between 2000 Q4 and 2004 Q4.

At its peak, in 2000, the electrical and instrument engineering sector accounted for 58 per cent of Scotland's manufactured exports. This industry remains Scotland's largest exporting sector and accounted for 34 per cent of Scotland's total manufactured exports in 2006.

Suppression of detailed engineering indices for the latest quarter

Due to a risk of disclosure of individual company exports information, it has been necessary to suppress the 2007 Q2 figures for two of the detailed engineering series (transport equipment and mechanical engineering) in order to safeguard contributor confidentiality.

The suppression of these cells will be kept under review, and should subsequent revisions to this series reduce the risk of disclosure to an acceptable level these cells will be published in future.

BACKGROUND NOTES

Methodology

1. Estimates of Scottish manufactured exports are compiled on the standard industrial classification UKSIC(2003). Implemented on 1 January 2003, UKSIC(2003) is a minor revision to UKSIC(92), in line with the latest revision of the European Union classification system.

2. 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) collect the data used to produce these figures in their Monthly Production Inquiry. Export estimates for the refined petroleum products industry are calculated using a volume series supplied by the Department of Trade and Industry and export ratios estimated using the Scottish Government's Global Connections Survey.

3. The main purpose of the Index is to identify volume changes over time. Accordingly, data are deflated to 2000 prices using UK export producer price indices, which are produced by the ONS. These constant (2000) price estimates provide a more appropriate measure for monitoring change over time as they have had the effect of price changes removed.

4. Deflated exports sales of the companies covered by the Inquiry are grossed up to represent the entire population of each industry using the Inter Departmental Business Register.

5. Cross-referencing of company information from the Global Connections Survey (GCS) is carried out annually to enhance the level of consistency between individual company records held in both sources. GCS annual data are currently only available for calendar years 2002 - 2005, so rescaling of pre-2002 data takes place to ensure continuity.

6. The data have been seasonally adjusted where appropriate using the X-12-ARIMA technique. Further information is available in an article published in the 2006 edition of Scottish Economic Statistics.
( http://www.scotland.gov.uk/stats/ses/).

7. In total, the Index is based on a sample of around 1,000 Scottish manufacturing companies per quarter. This sample covers all sizes of unit across the manufacturing sector.

The Global Connections Survey

8. The annual Global Connections Survey (GCS) provides a current price cash estimate of the value of exports sales for the economy as a whole; the only survey to do so. The Quarterly Index of Manufactured Exports provides a time series of growth in export sales, at constant prices, for the manufacturing industry. The annual estimate of total exports from Scotland derived from the Global Connections Survey indicates that the manufacturing sector accounted for £13.1 billion in 2005 - 70 per cent of all exports from Scotland.

9. Further information about the methodology of the Index of Manufactured Exports and the Global Connections Survey can be found on the website at www.scotland.gov.uk/exports

Volatility

10. Some of the indices for smaller industries can be particularly volatile when examined on a quarterly basis. In some cases, this is due to the nature of the industry (e.g. transport equipment), in others it can be due to the relatively small size of the industry in export terms (e.g. food & tobacco). For these reasons, care should be taken when drawing any firm conclusions from individual quarter results. Estimates of annual changes will be more robust than quarterly changes.

Revisions

11. It is the Scottish Government's policy to use all the data available at the time of publication to ensure that the best possible estimates are provided. This inevitably leads to revisions to previously published estimates. All quarters affected by data revisions are updated at the earliest possible opportunity. This allows those using the data for long-term analysis to have a long-term consistent series. We have a commitment to improve continually the quality of the index of manufactured exports, and part of this commitment involves an ongoing programme to develop the data sources and methodologies used in the compilation of the series.

12. The chart above shows a comparison of the overall index this quarter and the index published in April 2007. Revisions this quarter are minor.

13. Tables 3 and 4 provide detailed information of revisions at industry level. Quarterly revisions which balance out to zero over the year indicate that there has been a change to the seasonal pattern of the series rather than a revision to the data for any companies.

14. The industries most affected by the incorporation of updated and revised data are mechanical engineering (due to revisions to data held on a small number of companies for a number of recent quarters) and drink (due to revisions to seasonal adjustment factors).

Future Revisions

15. Company data used to create the Index of Manufactured Exports is cross-referenced annually with the Scottish Government's Global Connections Survey (next published with 2006 data in December 2007). These benchmarked data will be incorporated into the next Index of Manufactured Exports release (covering data from 1995 Q1 to 2007 Q3). This may lead to revisions to previously published data.

National Statistics

16. National Statistics are produced to high professional standards set out in the National Statistics Code of Practice. They undergo regular quality assurance reviews to ensure that they meet customer needs. They are produced free from any political interference.
