As part of a bigger research project I am looking at county level retail sales and a variety of population and labor measures so I took a quick stab at mapping out how this looked. The map is for sales per establishment. If you do not normalize by something the map is useless, though what the proper normalization is part of the question. What is interesting is the relative degree of uniformity in sales per establishment. This is a consistency, not a perfect uniformity. It is really surprising where there are hot spots and where there is just more of the same. Gray shaded counties have data suppressed due to privacy concerns and white filled ones are not in the economic census for some reason.
