This legislation amends the Social Security Act to establish a comprehensive program designed to address social isolation and loneliness among older individuals and adults with disabilities. It authorizes the Secretary to provide grants to area agencies on aging and other community-based organizations. These grants are specifically for conducting outreach to individuals at risk, developing community-based interventions to mitigate loneliness, and connecting these individuals with vital social and clinical supports. The bill appropriates $62,500,000 annually for fiscal years 2026 through 2030 to fund these initiatives. Beyond grants, the bill also mandates the establishment of training programs for these organizations to enhance their capacity in addressing and preventing social isolation. The Secretary may prioritize training models that integrate with medical-legal partnerships to better connect at-risk individuals with existing supports. Furthermore, the legislation requires the Secretary to submit a report to Congress every three years, evaluating the effectiveness of the programs in reducing social isolation and loneliness among the target populations, and mandates coordination with other relevant federal programs.
