What I want to see is the the change in the percent of people who only have access to one brand umbrella of large grocery store crosstabbed against various distances (5,10,20 miles). Will this take the number of people with a single brand of grocery stores within 10 miles from 10% to 20% or 5% to 7%? I really have no idea.
