A more thorough explanation:

Definition: Volunteers in Service to America, also known as VISTA, is a federal program that was established in 1964. Its purpose is to provide volunteers who can help improve the living conditions of people in the poorest areas of the United States, its possessions, and Puerto Rico.

Examples: VISTA volunteers work in a variety of areas, including education, healthcare, and community development. For example, a VISTA volunteer might work in a low-income school to help students improve their reading skills. Another volunteer might work with a community organization to develop programs that address poverty and unemployment in a particular neighborhood.

These examples illustrate how VISTA volunteers work to improve the lives of people in need. By providing their time and expertise, they help to address some of the most pressing social issues facing our country.
