The Diversity of Cultural Participation in the Arts

Just doing some research on participation in the arts, and wanted to share a bookmark to an interesting article I found: http://www.wallacefoundation.org/KnowledgeCenter/KnowledgeTopics/CurrentAreasofFocus/ArtsParticipation/TheDiversityofCulturalParticipation.htm

I'd be interested in any thoughts folks have surrounding participation and the arts (or links to relevant research articles)...
