About the Data: The Centre for Retail Research estimated the trends in online retail sales for eight European countries (see above) and the US. The estimates are based on the sales of goods (excluding fuel for vehicles and sales of prepared food in cafes and restaurants). Tickets, holidays, gambling and insurance are also excluded because they are not classed as retailing. ‘Online’ is defined as sales where the final transaction is made over the internet or at a distance, irrespective of whether the internet has been used for browsing and price comparisons. Sales made using mobile phones and tablets are included in the figures.
One thousand shoppers in each country (a representative demographic cross section) were surveyed for the project as were 100 online traders in each country.
