WASHINGTON (AP) — A new report finds that billions of dollars in arts funding is serving a mostly wealthy, white audience that is shrinking while mostly ignoring emerging art groups that serve poorer communities that are more ethnically diverse.The report from the National Committee for Responsive Philanthropy, a watchdog group, shows foundation giving has fallen out of balance with the nation's increasingly diverse demographics. The report was provided to The Associated Press before its release later Monday.It says the largest arts organizations representing only 2 percent of the nonprofit arts and culture sector received 55 percent foundation funding for the arts. Only 10 percent of arts and culture grant dollars were dedicated to underserved populations.The study calls for broader funding to make philanthropy more relevant and effective.
