The results contained in this release reflect some of the economic impacts of the COVID-19 situation. In general, for the Industrial Production and Turnover indices, the CSO recommends that commentary and interpretation of the results should focus mainly on the monthly unadjusted series and on the seasonally adjusted three-month moving average. The CSO will continue to review how the seasonal adjustment models are applied to the series on Industrial Production and Turnover, and may introduce revised estimates. For further information see: Information Note - Industrial Production and Turnover Index March 2022.

Notice of Revisions: The Industrial Production and Turnover Indices were revised on 13th December 2021. See here for further information.

go to full release

Production in manufacturing industries was 12.9% greater in the three months January 2022 to March 2022 than in the preceding three months. See Headline Table and Table 3b.

On an annual basis, production in manufacturing industries was 5.7% lower in March 2022 than in March 2021. See Headline Table, Table 1 and Table 3a.

In Quarter 1 2022, production in the “Traditional” sector was 22.5% greater than in Quarter 1 2021, when many industries were impacted by COVID-19 related restrictions. Over the same period, production for the "Modern" sector decreased by 20.2%. See Table 2.

Production in the Electricity, gas, steam and air conditioning sector increased by 5.7% in the three months from January 2022 to March 2022, compared to the same period last year. See Table 3b.

Turnover in manufacturing industries was 3.2% greater in the three months from January 2022 to March 2022 than in the preceding three months. See Headline Table and Table 5b.

Adjusted and unadjusted indices are available on CSO PxStat

1The figures from March 2020 onwards are an exception to existing seasonal patterns and have highlighted the underlying volatility of the monthly industrial production and turnover series. Seasonal adjustment is challenging in the current climate and while the seasonal adjustment models have been reviewed and changed as appropriate (e.g. by treating the data for certain sectors as additive outliers) the underlying volatility of the data is still reflected in the seasonally adjusted series. The CSO is continuing to review how the seasonal adjustment models are applied to the series on Industrial Production and Turnover, and may introduce revised estimates.

Background Notes

Introduction  

Industrial Production and Turnover (IPT) monitors the volume of production and value of turnover of industrial local units. Two indices are compiled from the survey – the monthly index of production and the monthly index of turnover.

The monthly index of production measures the change in the volume of production (i.e. value added at constant prices) each month. 

The monthly index of turnover measures the change in the level of sales each month of industrial products, whether manufactured in the month in question or in previous periods (excluding non-industrial activity where practicable). The turnover indices outlined in this release are exclusive of VAT. 

The principal difference between the production and turnover indices is that the production index traces the quantitative volume of production (i.e. with the effect of price changes excluded) each month whether sold or not, whereas the turnover index reflects both the volume of sales and the price level.  

Starting with January 2015 updated industrial production and turnover indices are being published to base year 2015=100. 

Sample covered

Industrial Production and Turnover covers all the larger local units which between them account for the bulk of industrial output – in general those which in the base year 2015 had twenty or more persons engaged in NACE divisions 5 to 35. For certain sectors the threshold of 20 persons engaged is lowered where this is considered necessary to ensure representativeness of the sample or where data for a sector would have to be kept confidential if a threshold at 20 persons engaged was applied. The business activity classifications are based on the Statistical Classification of Economic Activities in the European Community (NACE Rev. 2).

The provisional results are published about 40 days after the reference month. At that point, the response rates are typically 46% of local units surveyed covering 84% of the value of production and 82% of the value of turnover. The corresponding figures for the final results, one month later, are 66%, 95% and 94% respectively. These response rates are based on averages for the 12 months of 2017. 

Methodology

Index calculation

Individual turnover sub-indices are compiled for each detailed NACE class (i.e. NACE 4-digit level). These sub-indices are combined to provide the indices for broader sectoral groupings (NACE 2-digit and groupings of NACE) using the turnover as the weight.  The production indices are created in the same way but use the gross value added at factor cost (GVA) as the weight. The production indices are calculated at constant prices, using the Wholesale Price Index (Base 2015 = 100) as deflators. The GVA and turnover weights are from the 2015 Census of Industrial Production (CIP). The weights and base year are revised every five years. 

Globalisation and Measurement of Industrial Production

The level shift of 26% in GDP in 2015 was driven by relocations of entire balance sheets to Ireland, with the activity related to these relocations having consequential impacts on the corresponding annual and monthly industrial statistics. These relocated balance sheets were dominated by intellectual property. The practice of relocating intellectual property to Ireland has been growing in recent years, but the scale of the relocations in 2015 was substantial and added €300 billion to Ireland’s capital stocks.

Associated with the relocations were significant increases in contract manufacturing activity attributable to Ireland. While contract manufacturing and outsourcing arrangements – both by Irish and foreign-owned enterprises - were not new per se, the level of increase seen in 2015 was substantially greater than in previous years. The Index of Industrial Production increased by 33% between 2014 and 2015.

The CSO’s treatment of contract manufacturing in the IPT follows the definitions set out in the UN 2010 International Recommendations for the Index of Industrial Production. The relevant section of the UN recommendations, on the treatment of outsourcing activities is as follows:

 

"Outsourcing of parts of the production process

If only part of the production process is outsourced, the principal is classified to the ISIC class that corresponds to the activity representing the complete production process, i.e., it is classified as if it were carrying out the complete process, including the contracted work, itself.

This applies not only to the outsourcing of support functions in the production process, such as accounting or computing activities, but also to the outsourcing of parts of the core production process, such as parts of a manufacturing process.

Outsourcing of the complete production process

In general, if the principal outsources the complete production process of a good or service, it is classified as if it were carrying out the production process itself. This applies in particular to all service-producing activities, including construction.

In the case of manufacturing, however, the following special considerations apply. In manufacturing, the principal provides the contractor with the technical specifications of the manufacturing activity to be carried out on the input materials. The input materials (raw materials or intermediate goods) can either be provided (owned) by the principal or not.

A principal who completely outsources the transformation process should be classified into manufacturing if and only if it owns the input materials to the production process – and therefore owns the final output." 

On the basis of these recommendations outsourced production is included as part of an enterprise’s Irish production. The inverse (i.e. Irish companies being sub-contracted to produce for foreign companies) has been excluded to avoid double counting.

The PRODCOM annual survey provides statistics on domestic production sold in Ireland annually.  

Seasonal Adjustment 

Seasonal adjustment is conducted using the direct seasonal adjustment approach. Under this approach each individual series is independently adjusted, i.e. aggregate series are adjusted without reference to the component series. Seasonal adjustment models are developed for each series based on unadjusted data spanning the months from January 2000 to the current period. These models are then applied to the entire series. Seasonal factors are updated each month.

The adjustments are completed by applying the X-13-ARIMA model, developed by the U.S. Census Bureau to the unadjusted data. This methodology estimates seasonal factors while also taking into consideration factors that impact on the quality of the seasonal adjustment such as:

• Calendar effects, e.g. the timing of Easter

• Outliers, temporary changes and level shifts in the series 

For additional information on the use of X-13-ARIMA see https://www.census.gov/data/software/x13as.html

NACE classification

The business activity classifications used in this Statistical release are based on the Statistical Classification of Economic Activities in the European Community i.e. NACE Rev. 2. For further information on the NACE Rev. 2 classification of industrial activity, see NACE Coder.

Definitions

All industries are comprised of all sectors classified NACE 05 to 35 inclusive. This includes Mining and quarrying NACE 05 to 09, Manufacturing Industries NACE 10 to 33, Electricity, gas, steam and air conditioning supply NACE 35.

"Manufacturing Industries"

Manufacturing Industries is comprised of all sectors classified NACE 10 to 33 inclusive.

"Transportable Goods Industries"

Transportable Goods Industries is comprised of all sectors classified NACE 05 to 33 inclusive. This includes Mining and quarrying NACE 05 to 09 and Manufacturing Industries NACE 10 to 33.

 “Modern” Sector

The Modern Sector includes the following industrial sectors:

NACE 20.00 - 21.20 Chemicals and pharmaceuticals

NACE 26.00 - 27.90 Computer, electronic, optical and electrical equipment

NACE 18.20 Reproduction of recorded media

NACE 32.50 Medical and dental instruments and supplies

"Traditional” Sector

The Traditional Sector includes All Industries (NACE 05 to 35) excluding the “Modern” sector as detailed above.  

Wholesale Price Index (Base Year = 2015)

The wholesale price indices were revised in March 2018 to include updated weights (base year = 2015). New base year weights were compiled for the Wholesale Price Index using the results of the 2015 Census of Industrial Production (CIP) and the Prodcom Inquiry surveys. New base weights were applied to each three digit NACE group on the basis of the Census of Industrial Production and the commodity group weights were assigned on the basis of the Prodcom Inquiry. For further information on the updated WPI indices see the CSO publication Revised Wholesale Price Index Introduction to Series 2015=100 (PDF 416KB) .
