Information Note on the Implications of COVID-19 on the Quarterly National Accounts - Quarter 3 2020

Data for the Quarterly National Accounts (QNA) are collected from a broad range of sources across all sectors of the economy. The results are based on release data compiled directly by CSO, administrative data sources and responses to CSO surveys. Despite the current difficult circumstances relating to the COVID-19 pandemic, many data suppliers have continued to provide us with this statistical information and we wish to thank all survey respondents for their continued support.

However, due to the temporary closures relating to COVID-19 and the difficulties faced by all participants in the economy, including businesses, households, government, charities, not-for profit institutions and other economic entities, the response rate for certain CSO surveys were lower than normal in the July to September 2020 period, for example the response rate for the September Retail Sales Index (RSI) survey was about three percentage points lower than the corresponding month in 2019. For Industry, the response rate for the July, August and September 2020 Industrial Production & Turnover (IPT), was lower in certain NACE groups than normally expected. It is hoped that businesses will be in a position to provide CSO with the data at an appropriate future date.

Imputation
While the overall Personal Consumption Expenditure (PCE) aggregate remains a robust indicator of trend, owing to the COVID related temporary closures, classification of PCE at the sub-aggregate level has proved more difficult due to more limited data availability. The unavailability of certain normally available data source breakdowns between goods and services, with the consequent need to examine and utilise supplementary alternative data sources such as Central Bank Credit and Debit Card data, has led to the goods and services sub-breakdown estimates being of somewhat lower reliability than usual. This circumstance will be kept under continual review and as and when further data observations become available in the months and quarters ahead, from traditional sources as well as from new sources such as the Credit and Debit Card data, revisions to the sub-element breakouts will take place accordingly that should improve the quality of the sub-breakdown estimates. Additionally, processes for capturing new PCE economic activity emerging as a result of the COVID-19 impact are under development and being kept under constant review.

Seasonal Adjustment
The March 2020 figures, and those for subsequent months, have been an exception to existing seasonal patterns. It must be recalled that the most severe and acute impacts of the COVID-19 restrictions affected Q2 but only partially affected the month of March and therefore the full reference quarter Q1 2020 was not impacted by the full severity of the pandemic (in actuality it significantly affected approximately 20% of the 91 days of the quarter). Seasonally adjusting the Quarterly National Accounts will remain challenging until the scale and shape of the impact COVID-19 has on the time series is better understood.  For the time being the Q1, Q2 and Q3 2020 reference quarters have been modelled as additive outliers (AO) which will be reviewed as required. We have tested the data and treated Q1, Q2 and Q3 2020 as additive outliers for certain sectors and other contributing elements to the accounts but not all. This treatment for seasonal adjustment purposes reflects the volatile nature of certain economic sectors more impacted by COVID than others, such as retailing & wholesaling, and the arts & entertainment sectors and shall be kept under review going forward as required. Users should be aware that as further data observations become available in the months and quarters ahead, revisions to the seasonal adjustment models may result in revisions to the quarterly seasonally adjusted series.

Eurostat Guidance
In compiling the Q3 2020 QNA, guidance issued by Eurostat has been followed as and where appropriate, specifically in relation to the compilation of Non-Market Output estimates. See Eurostat Methodological note - Guidance on Quarterly National Accounts (including flash) Estimates in the Context of the COVID-19 Crisis (PDF) and Eurostat Methodological note - Guidance on non-Market Output in the Context of the COVID-19 Crisis (PDF).

Weights
Index weights upon which most Fixed Base, Previous Year’s Prices and Chain Linked data are based in the Quarterly National Accounts are to base year 2015 (2015=100) and consequently may not reflect the full and entire current distribution of economic activity in certain sectors that has arisen due to the COVID-19 crisis.

July-September 2020
Many establishments were open for either a part of or most of March but were closed for late-March, April and May. Many retail outlets were still closed in May, with only a small number of sectors, classified as essential retail outlets on 27th March, allowed to open their shops for the whole of the month. On 18th May Phase 1 of the Roadmap for Reopening Society and Business commenced with further sectors free to reopen for business. These businesses included Opticians/optometrists; Sale, supply and repair of motor vehicles, motorcycles and bicycles; Hardware stores, builders' merchants and stores selling supplies and tools essential for gardening/farming/agriculture; Office products and supplies; Electrical, IT and phone sales, repair and maintenance services. On 8th June Phase 2 of the Roadmap for Reopening Society and Business commenced with all remaining retail sectors free to reopen for business. Most remaining retail outlets were permitted to reopen from 8th June while Shopping Centres were allowed to reopen on 15th June. Businesses that reopened on 29th June included pubs serving food, cafés, restaurants, hotels, hairdressers, beauty salons and tourist attractions. Level 3 restrictions were introduced in certain counties during the course of September. Data collection proved challenging for the entirety of the Q3 reference quarter and will continue to do so in the COVID environment.

The CSO wishes to thank all those households and enterprises who supplied their data for the months of July, August and September, as well as for Q1 and Q2, and encourage them to continue to do so for subsequent months, even for instance where turnover for many enterprises may be nil. Such information is still needed to measure the precise impact of the crisis on the economy. The CSO will also continue to monitor a range of supplementary source information, such as banking credit and debit card data referenced above, to derive the best estimates for economic growth in Q4 2020 which was affected by further restrictions from 21 October until 30 November. The Q4 QNA is planned for publication in the first week of March 2021.
