IMPACT Rank

Pragma’s IMPACT Gravity Model has been developed by an in-house team with the assistance of CASA (Centre for Advanced Spatial Analysis), part of UCL. The model is calibrated using Pragma’s wide range of consumer surveys; which to date have sampled over half a million shoppers across a range of locations across the country. This is supplemented further by analysis of the retail mix of over 2,500 retail locations in Great Britain. Floorspace, merchandise mix, Pragma’s FISH segmentation and retailer price points have all been analysed to make sure the model reflects real world observations as closely as possible.
