Maps Show Striking Link Between Car Commuting and Obesity

Check out these two maps, the first showing obesity rates (by county) in the United States and the second showing the percentage of commuters who travel by car (via Planetizen).

Researchers Anne Price and Ariel Godwin at Planetizen caution readers not to conflate correlation and causation. However, when comparing other economic and demographic characteristics (unemployment, educational attainment, income), no other maps displayed such striking similarities.

Furthermore, when the research team created a scatterplot comparing obesity rates in U.S. counties with commuting patterns, a "strong relationship" emerged.

Again, Price and Godwin were cautious about drawing a direct causal relationship:

Sounds like more research is needed -- in addition to more transportation choices in the southeast and Appalachia.

It would also be interesting to examine whether the availability of alternatives to single occupancy vehicle travel contributes to some of the better economic indicators in some of the nation's less obese, wealthier areas.
