We have been analysing the location strategy of many major retailers using AggData information. The depth of it is really great - every location for a large number of retailers.
We did an analysis looking at the average and overall draw for each retailer on a consistent basis and ranked the results in the table below.
How we did it: For each banner, we summed the population around each location that is closer to that location than any other. We included only population within 30km or 18.6 miles of each location. This eliminates overlaps and the problems they cause.
We then summed up the total draw for each banner to calculate its US Draw.
The sources are AggData for the locations and US census populations.
