Prior research has demonstrated ways in which community events help to establish age-friendly community initiatives and strengthen their impact. We extend these insights by discussing how the design and implementation of a statewide event - the New Jersey Age-Friendly Virtual Fair - exemplifies this practice theory and extends its applicability beyond local community development toward broader state-level age-friendly ecosystems. We describe how events that are deliberately multi-organizational, multi-sectoral, and multi-level can help to further propel the Age-Friendly Movement toward systems change for aging in community.
