Here is one of those, “Why’s that?” infographics from the Daily Statistic. Why are prices cheaper in Carracas and Riyadh, and so much more expensive in London and Oslow? Another way that this infographic might be used in math is to ask students to figure out how and then convert prices to U.S. or other local standards.
It might also be interesting to compare the map in this infographic to a map of the world that points to the producers of crude oil, such as this one. I wonder also, if there is a map or data somewhere on the per-capita use of SUVs around the world.
