This report profiles the nonprofit sectors in Arkansas, Nevada, and Oklahoma using data from the Forms 990 filed with the U.S. Internal Revenue Service. It compares the basic structures of the sectors in each state and examines the financial health and capacity of arts and cultural groups and human service providers. The findings show that, on average, nonprofit organizations in the three states are smaller and less well funded than their counterparts nationally. Strong reliance on private philanthropy was a common mechanism for easing financial vulnerabilities, but groups nonetheless operated on very small margins. The data suggest that the nonprofits in these three states are not fully utilizing available private and public sources of revenue and instead are relying heavily on special fundraising events and investment income to support their activities.
