Thanks again to the Adventure Cycling Association's Bike Bits e-mail newsletter for this link.
An editorial from the Janesville Gazette of Wisconsin reports on a recent study at the University of Wisconsin-Madison which states that the overall bicycle industry generates $1.5 billion in economic activity per year for the state. That compares just slightly higher than the $1.4 billion resulting from deer hunting, another popular industry in Wisconsin.
The bicycling figures include activity from cycling-related manufacturing based in the state, bicycle sales and service business, and bicycle-related tourist activities. $535 million is spent by cyclists from states outside of Wisconsin.
