The green dots on this map representing Starbucks locations which are obviously clustered in major metropolitan centers. Cross-referencing this Starbucks address location with population data, Davenport explains his mapping technique: "By counting the number of people who live within a given distance to each Starbucks, we can measure how well centered Frappuccinos are to the US citizenry. In other words: draw a 1-mile circle around every store, then add up the % of the population living within the circles. Repeat for 2, 3, 4....100 miles." The result of this data is a fabulous logrithmic S-curve which explains much about the American population distribution.

Earlier I have posted the classic image of "Earth Lights at Night," and discussed the classroom uses of the image. This cartogram helps take that analysis one step further. This cartogram helps students to visualize the magnitude of population (with the cartogram adjusting area for population) and then to see the patterns of energy use, global consumption and urbanization with in a new light.
