2. Main points

  • Gross domestic product growth in the North West was negative 0.7% in Quarter 4 (Oct to Dec) 2018.

  • Estimates of quarterly GDP in the English regions and Wales are published here for the first time, alongside data previously published by the Scottish Government and the Northern Ireland Statistics and Research Agency (NISRA).


These estimates are designated as Experimental Statistics and should be interpreted with some caution. Regional data can be volatile and quarterly movements should be considered alongside the long-term trend. To assist with this, quarter on same quarter a year ago data are published alongside the latest quarter-on-quarter estimates.

3. GDP in the North West

Gross domestic product (GDP) in the North West had negative growth of 0.7% in Quarter 4 (Oct to Dec) 2018, following positive growth of 0.8% in Quarter 3 (July to Sept) 2018. Compared with the same quarter of the previous year, GDP grew by 0.5%.

In Quarter 4 (Oct to Dec) 2018, the production and services sectors fell by 1.9% and 0.6% respectively, while the construction sector grew by 0.8%.

Relative to 2016, over the last two years the North West region had strong growth in the construction sector. The production and services sectors saw growth compared to 2016 but in Quarter 4 2018, there was a decrease in growth for both. In Quarter 4 2018, the growth in construction slowed but remained positive.

The real estate and construction industries grew by 0.5% and 0.8% respectively and were the largest positive contributors to growth in the North West, at 0.06 and 0.05 percentage points respectively. Meanwhile, manufacturing fell by 2.1% and was a major negative contributor in the region. The production and services sectors both contributed negatively to GDP growth in Quarter 4 (Oct to Dec) 2018 within the North West. The main drivers of the falls within these sectors were manufacturing, which contributed negative 0.33 percentage points, and education, which contributed negative 0.18 percentage points.

6. Measuring these data

The main data for these estimates are turnover data from approximately 1.9 million Value Added Tax (VAT) returns. Information from the Inter-Departmental Business Register (IDBR) on workplace employment allows us to apportion the VAT turnover for each business based on their employment share within a region. There is also a quality assurance of administrative data (QAAD) report for VAT data.

Other volume measure data are used where appropriate, or where VAT data has insufficient coverage. A full list of other data sources is included in the methodology article.

Detailed methodology for these statistics is available.

A detailed analysis of these new data is planned for the Economic review to be published in October 2019.

7. Strengths and limitations

These data are designated as Experimental Statistics. These are statistics that are in the testing phase and not yet fully developed. We will continue to develop these statistics and seek users’ views on their use and needs for these data.

While the data sources and methods used in both our regional and national estimates of gross domestic product (GDP) are broadly similar, there are some clear differences. For example, in the extent to which Value Added Tax (VAT) data are used.

This means that while regional GDP aims to produce the best estimates at a regional level, the sum of the regions (adding in published estimates for Scotland and Northern Ireland) may not equal the national total. To address this, we have constrained our regional GDP estimates to the national totals in such a way that minimises changes to the region by industry quarter-on-quarter growth rates. The overall impact of this constraining on the regional estimates is small.

There are different possible methods available to us for carrying out this constraining. We continue to examine the impact of the range of different methods before deciding which one is best suited to these data in advance of applying to be assessed as National Statistics.

Please note that the one industry that is not fully constrained is mining and quarrying. In this industry there were challenges in chain linking the data from the regional accounts. We will address this in the regional accounts publication in December 2019 allowing subsequent quarterly releases to be fully constrained.

As part of the quality assurance process the Department for Environment, Food and Rural Affairs (Defra) notified us that they have improved their methodology for estimating regional breakdowns of the agricultural accounts. Defra has since provided us with data produced using the new methodology but unfortunately we were unable to process that data in time for this release. Data based on the old methodology is included in the compilation of headline GDP for the English regions and Wales, but will have little effect on these aggregates given the comparatively small size of the agriculture industry. However, we have taken the decision not to include a breakdown of agriculture in this release and we will process the new data and provide a breakdown in our Quarter 1 (Jan to Mar) 2019 release.
