Datacentre gives you key figures and forecasts to help you build strong business plans. It covers over 400 of the world’s largest retail groups and almost 1,000 operations.
Our interactive tool makes it quick and easy to create customised data reports for the retailers, markets and channels you need. IGD’s team of global retail analysts ensure the numbers are robust and reliable, giving you the confidence to put them at the heart of your planning and assessment.
Our primary research programme sets us apart. Our unique retailer and supplier relationships enable us to get to know markets from the ground up. We build our insights through our global research and travel programme, backed up by comprehensive desk-based research. We take insights from a wide range of sources, including company reports, releases and filings, analyst briefings and research notes, regulatory bodies and global news services.
Our figures are based on published retailer results, with an estimate for channel/format breakdowns (as not all retailers provide this breakdown).
We use market size data from national statistics offices, so we have a common methodology across all the countries we cover.
View our measure, format, and country definitions.
We use retailers’ past performance and our knowledge of their future plans to update our forecasts.
Often that information is taken from the retailer’s published annual reports, and their press releases. In other cases, we use a variety of sources, including our own contacts around the world and our experience of visiting retailers and their stores. Our primary measures are Sales, Stores, and Space.
When we forecast, we look at the retailer’s past performance in each market and channel, how that market and channel are evolving, and how economies are expected to behave. We bring all these factors together to project five years into the future. As we do that, we keep an eye on what that does to competitors’ relative positions in the market.
This is a calculation the team can carry out for you, based on the retailers we track in Datacentre. Please contact [email protected]
We aim to update numbers for significant retailers one month after they publish their results. This may take longer for smaller retailers.
Contact [email protected] to find out which are estimates and actuals.
The retailer sales are in nominal terms (or current prices), which means they include inflation. These figures exclude VAT, as do our modelled market sizes.
You can calculate the real values by using the Consumer Price Inflation measure in the tool, in the ‘Add Measures’ section. You can arrive at real values by taking inflation away from nominal sales.
Where possible, we record financial performance data in domestic currencies.
The exchange rates are updated on an annual basis, using the average prices for the year.
Note that these exchange rates may differ from those used by retailers, and therefore lead to differences to published figures.
Companies operating grocery stores have many different organisational structures. We use a standardised approach to manage this variation:
Do you cover all retailers?
We aim to include the key retailers in every market we cover, though there will be some we don’t track (we do not include traditional markets, independent retailers, forecourt operators or symbol groups, for example). However, we are always working to improve Datacentre, so do contact us if there’s a retailer you would like to see.
A: No. Datacentre records sales from the main retailers in each country. The sum of these retailers' sales therefore excludes smaller retail outlets and traditional trade that we don't track.
A: Please contact Kantar for information on their methodology, although a key difference is that Kantar figures are based on shopper survey results whereas IGD uses national statistics and published retailer results.
We publish our own annual market shares. Visit the ‘Market’ section at the top of Retail Analysis, select the country you’re interested in, and click the ‘At a glance’ button in the orange tool bar. You’ll be shown a market share pie chart . The size of ‘other’ is made up of other modern retailers we don’t track, as well as traditional trade.
Separately, we do also publish 12-week UK Kantar market shares
IGD's market shares differ from panel-based or till-roll market shares (e.g. from Nielsen, Kantar Worldpanel etc) due to the different methodologies. The latter are based on limited categories/retailers and use different definitions of the 'grocery retail market'. Find out more about our methodology here.
A: Non-grocery sales are the sales from a retailer’s specific non-grocery operations (eg Financial Services, Property, or Fuel). Non-grocery items sold within majority grocery stores (Supermarkets, Convenience stores, etc) are included in grocery sales, since they will only comprise a small proportion of total sales.
Q: Where can I find compound annual growth rate (CAGR)?
A: This is a specialised calculation the team can carry out for you. Please contact [email protected]
Q: Can I get channel growth by region?
A: This can be calculated based on the sales by format of the retailers we track. The team can carry out this calculation for you. Please contact [email protected]
