A more thorough explanation:

A nonprofit association is a group of people who come together for a common purpose that is not to make money. This can include organizations that focus on science, religion, education, or charity. Nonprofit associations are not separate legal entities from the people who make them up, unless they have certain corporate attributes like centralized management and limited liability.

Examples of nonprofit associations include:

• A charity that raises money to help people in need
• A group of scientists who work together to advance their field
• An educational organization that provides resources and support for teachers

These examples illustrate how nonprofit associations are formed around a shared goal or interest, and work together to achieve it without the primary goal of making money.
