According to a 2009 US Fish and Wildlife Service survey, over 45 million hunting licenses were sold in the US that year, generating $764 million in revenue. All hunting license revenue is used to fund conservation efforts and agencies like park rangers and wildlife biologists in each state. The author analyzed state-by-state hunting license sales data to understand geographic patterns and show the positive impact of hunting on conservation. States with the highest license sales tended to be more rural and agricultural areas with strong hunting traditions.
