We received this inquiry today via email, and thought you'd find it intriguing. Offered, temporarily, without comment.
I saw that you recently published a commentary on the recent news of Dollar Tree's acquisition of Family Dollar. On this note, I thought that you might be interested on our most recent project, which looks at dollar stores and household income.
Looking at household income, turns out, is a pretty good clue in determining where the dollar stores are in the country. While Texas may have the most dollar stores, for example, it's Mississippi that has the most dollar stores per capita. Interestingly enough, both states have household incomes below the national average. And so we created "The Dollar Stores of America", a visualization that captures the relationship between dollar stores and household income.

Perhaps it could be an interesting topic for a future article or something to share with your readers. Feel free to also read our article on dollar store trends in the Silicon Valley area, which you can find here: http://www.retale.com/blog/silicon-valleys-wealthy-tech-workers-arent-bothered-with-dollar-stores/
