Tesco may be twice as powerful as previously thought
Using its predictive modelling system CACI is able to estimate the market share of all the key retailers within each Postcode Area (indicated by the prefix letter(s) of a postcode i.e.WD, AL etc), on the basis of supermarket (stores over 4,000 sq ft) locations and sizes, plus additional data such as national and regional market share, and local demographics.
Performing this exercise across the whole of the UK, CACI estimates that Tesco has now achieved market leadership in as many as 81 of all 121 Postcode Areas (67%). Furthermore it also estimates that in the 40 remaining Postcode Areas, Tesco holds the number two spot in 24. Therefore there are just 16 Postcode Areas (13%) in the country where Tesco does not hold the number one or two spot.
