Making the blog rounds today is a discussion of Starbucks Density as a data point of any given location. I propose we extend the concept and calculate the Relative Starbucks Density, which is obtained by dividing the Starbucks Density by the Coffee Houses & Cafes Density for the same location using Google Local.

For instance, the R.S.D. at work in Berkeley is .29 versus an R.S.D. of .71 at home in Walnut Creek. This is to be expected.
