Environmental advocates, civil rights groups, and public awareness promoters all fall into the Third Sector. Some groups work on a very local level while others are national and international in scope, and everyone will, at some point, take advantage of the services they provide. While the number of organizations is large, and their missions widely different, they all share the common goal of serving the public by mobilizing donors and volunteers in a belief that individuals coming together for a shared purpose can make a difference in the world we live in.
The Third Sector is grouped together according to the services they provide. The organizations within the group often serve similar if not identical functions such as within education. With education as a common denominator, the institutions will work together to promote the value of their services and work to provide greater availability and access. Groups will form coalitions to lobby for effective legislation that will allow them to function more effectively. Often times, groups such as the Red Cross and hospitals will share resources in an effort to deal with a natural disaster.
