The executive summary of the report on key results from two investigative efforts--an online, national survey of outdoor arts festivals and seven case studies--to examine the range and variety of arts festivals in the U.S., the artists they employ, the communities they serve, and the roles they play in our cities, towns, and neighborhoods.  The survey collected, for the first time, comprehensive data on a large cross-section of U.S. arts festivals, including information about audiences, arts programming, budgets, and operating structure.
