Thanks in part to declining corporate, foundation, and government support, more than half the arts and cultural organizations in southeastern Pennsylvania operated with deficits in 2009, a report from the Greater Philadelphia Cultural Alliance finds. Based on data collected from 276 nonprofit arts groups, 2011 Portfolio (39 pages, PDF) provides a snapshot of the breadth, diversity, and financial and programmatic health of the region's arts sector, including the effects of the recession. The report finds that between 2007 and 2009 revenue fell 12 percent — and 43 percent, when investment revenue is included — while attendance rose 5 percent. The report also found that individuals were the greatest source of support during the recession, with admissions, tickets, and tuition revenue up 11 percent during the period, membership and subscription fees up 8 percent, and individual donations up 20 percent, while all other sources of income declined. Funded by the Pew Charitable Trusts, the William Penn and Dolfinger-McMahon foundations, and PNC, the report emphasizes the need for arts organizations to build deeeper relationships with audiences, retain talented personnel, and adapt to new business models.
