Dr. Patrick Rooney discusses how high net worth donors give a lot to different types of legal charities, including religious organizations, basic needs, education, social and racial justice, arts and culture, and animal and environmental causes. Additionally, he reveals that upwards of 90-95% of high net worth households donate, with only 9% having formal giving vehicles such as donor advised funds, and 30% volunteer formally through a 501(c)(3). Rooney explains that volunteering can slow mental decay and that charities are more likely to receive gifts from people who volunteer for them. These findings are discussed in Chapter 32 of Achieving Excellence in Fundraising.
