Mapping, Visualization

At a store near you…

Wal-Mart, McDonalds, Starbucks… There seems to be one around every corner.  Can you guess how close you’re to one? I had the 2010 Census data and when I came across store locations for Wal-Mart at GeoCommons I built this viz in Tableau.  Each pixel is the centroid of a census tract. Turns out 12 percent of the US population live within 2 miles of a Wal-Mart Store! This is an interactive viz but unfortunately WordPress doesn’t allow embedding it into this page 😦 at this point in time. You can click on the image to open the interactive version in a new window.

Just how close are you to a Walmart? (Click to open interactive viz)

Store DensityIn addition to closest store, I calculated a density metric by adding up inverse distances of all Wal-Mart store locations for each census tract which is shown on the left. The areas with higher density of stores are shown in light green.
