Nonprofit organizations have three main needs: 1) to create campaigns to stimulate public interest in their goals, 2) to develop strong staff and utilize volunteers to handle large amounts of work, and 3) to establish realistic fundraising goals and plans. Nonprofits break down into three main groups: membership organizations, advocacy groups, and social organizations. The primary role of public relations for nonprofits is to raise money and awareness through various campaigns and fundraising methods to finance organizational expenses and projects, as they are tax-exempt organizations that provide benefits to members and society.
