Shared site intergenerational programs deliver ongoing services and shared programming to youth and older adults in a single setting. With the potential to benefit youth, older adults, families, and communities, they attract growing attention from practitioners, researchers, funders, and policy makers. Using national survey data we profile characteristics of 95 shared sites. Responding programs connected over 25,000 youth and older persons in 2017. The most common models consisted of adult day services and early childhood programs (i.e., preschool or childcare), though unique models offered diverse opportunities. Current priorities and challenges can be addressed with systematic data collection and access to resources, including incentives in the 2020 reauthorized Older Americans Act. (author abstract)
