The Multigenerational Care and Support Act amends the Older Americans Act of 1965 to significantly expand opportunities for older individuals to participate in multigenerational activities and volunteer roles. It redefines the focus of certain projects to explicitly serve both younger and older individuals through intergenerational engagement, promoting shared experiences and mutual support. This includes creating new avenues for older individuals to serve as mentors to younger generations. The bill specifically targets facilities that cater to either age group, such as multipurpose senior centers, long-term care facilities, and other residential facilities for older individuals, broadening the scope for these activities. By fostering greater civic engagement and support across different age groups, the legislation aims to enhance community well-being and intergenerational connections.
