How we sample

WE SAMPLE THE POINTS OF SALE ACCORDING TO THE CITY'S LANDSCAPE

RESTAURANTS The sampling is based on the average meal price, the cuisine and the format of the restaurant (hotel restaurants or high-street restaurants).

WINE SHOPS The sampling is based on the type of stores (independent shops or group owned) and the format of the store brand (with or without e-commerce platform).

GROCERY RETAILERS The sampling is based on the format of stores (supermarket or hypermarket) and the number of stores per retailer brand (with or without e-commerce platform).

INTERNET RETAILING The sampling is based on the web traffic. We select the top 50 online retailers by traffic.
