Older Americans Act
To meet the diverse needs of the growing numbers of older persons in the United States, President Lyndon Johnson on August 14, 1965, signed into law the Older Americans Act (OAA). The OAA set out specific objectives for maintaining the dignity and welfare of older individuals and created the primary vehicle for organizing, coordinating, and providing community-based services and opportunities for older Americans and their families.
