Joe Cortright is an economist and director of City Observatory, a virtual urban policy think tank that receives support from Knight Foundation. Last week we launched City Observatory, a new data-driven platform for sharing, analyzing and discussing the success of cities. The site’s original analysis and in-depth research on cities and urban issues is designed to inform community leaders, policymakers, policy wonks and the rest of us. Today we released “The Young and Restless and the Nation’s Cities,” a new CityReport that analyzes the choices young, educated professionals are making about where they live and how those choices are reshaping the economic development process. Future reports will address topics such as city job growth, neighborhood change, and the ways we create, use and interact with public spaces in cities.
