These funds allow donors to support a broad area of interest (such as education, the arts, or health care) without being tied to specific organizations or projects. This flexibility means the fund can respond to changing needs and emerging issues within that field over time.
For donors who want to make a difference but may not have the time or resources to thoroughly research individual charities or projects, contributing to a general field of interest fund simplifies the process. They can trust that their donation is being used wisely within their area of interest.
