The Older Americans Act (OAA), signed into law by President Lyndon B. Johnson on July 14, 1965, is not a standalone organization but a landmark federal statute that created the foundational infrastructure for aging services in the United States. Designed to address the lack of community-based support for older adults, the OAA established the Administration on Aging (AoA) and authorized grants to states for planning, delivering, and expanding social services, research, and training in the field of aging. Over the past 60 years, the OAA has evolved into the nation’s primary vehicle for delivering social, nutrition, and community-based services to older Americans. Its hallmark achievement is the creation of a robust national Aging Network, comprising 56 state units on aging, more than 600 Area Agencies on Aging (AAAs), thousands of local service providers, and hundreds of tribal organizations. This network coordinates critical programs such as home-delivered and congregate meals, transportation, in-home care, caregiver support, legal assistance, and elder abuse prevention. Key milestones include the 1972 establishment of the national nutrition program and the 1973 creation of AAAs, which decentralized service delivery and empowered local communities to tailor programs to their unique needs. Today, the OAA serves over 14 million older adults annually—delivering more than 250 million meals, 14 million rides, and 30 million hours of in-home and caregiver support each year. Notable for its enduring impact, the OAA remains a model of public-private partnership and scalable service delivery, leveraging technology and data to optimize outreach and efficiency. Its success underscores the value of investing in community-based solutions, making it a compelling case study for business and technology leaders interested in scalable, human-centered innovation.
