Purchasing power of the US Dollar (in Big Macs)

July 1, 2015 09:00 AM

In 2000, the average cost of a Big Mac was $2.51 and the average American consumed 7.7 gallons of whole milk. In 2009, those changed to $3.57 and 5.7 gallons, respectively. Over the 10-year period the two data points inversely correlated to 98.4%. Coincidence? Definitely. Or perhaps we can predict the decline of the purchasing power of the U.S. dollar using projected whole milk consumption.
