Seattle's Creative Vitality Index

While reading through CVI again, I noticed that 60% of the index is Community Arts Participation Index. It is comprised of these factors:

-Non-profit arts organization income (10%)
- Non-profit “arts-active” organization income (10%)
- Per capita bookstore and record store sales (8%)
- Per capita music store sales of instruments and equipment (8%)
- Per capita photography store sales (8%)
- Motion picture theater attendance (8%)
- Museum and art gallery revenues (8%)

My question is this: do you think this is an accurate picture of arts participation? What does arts participation mean to you?
