This paper examines the determinants of the demand for resident annual recreational fishing licenses across the upper-mid-west region of the United States. Statewide aggregate data was collected from North Dakota, South Dakota, Minnesota, Iowa, and Wisconsin in an attempt to understand what drives license sales across a national framework. Analysis of the results of an Ordinary Least Squares regression provides states with the opportunity to understand how much changes to the determinants affect license sales. It was determined that seven out of ten possible determinants provided significant results. Understanding of these determinants will allow states to improve efficiency of license sales, which in turn leads to higher revenue and better conservation efforts.
