Numerous amateur sporting events have grown significantly in stature and interest in the past several years. Moreover, these events have realized significant economic benefits for their respective communities. In an attempt to identify the key determinants of economic impact, this article offers numerous comparative economic impact data for amateur sporting events. The comparisons are across various categories, including the same event in different cities, the same city but different events, women’s versus men’s events, and events involving junior athletes compared to those involving senior athletes. Collectively, these comparisons demonstrate that the number and origin of nonlocal visitors, the proximity of teams involved, visitor spending patterns, length of stay, and operational and organizational expenditures by nonlocal entities affiliated with events are the largest determinants of economic impact for a given event.
