Cities are ground zero for the demographic shift that is changing America and the world, and city leaders are just beginning to understand the promise of an engaged older population. The urban landscape already holds resources—human, organizational, and technological—that can transform aging lives. From intergenerational mixed-use neighborhoods to smart city technologies and integrated housing and healthcare models, there is progress. But too many local leaders still overlook the connection between aging policies and their cities’ vitality and sustainability. They fail to consider their aging populations as they plan for economic development, and for housing, health, and infrastructure needs. Age-Forward Cities for 2030 offer a prescription for our urban future. By integrating population aging into strategies for growth, inclusion, and resiliency, cities can implement solutions that will strengthen how we grow, build, and care for generations to come.
