The fateful year 2020 brought dramatic challenges to American cities. The COVID-19 pandemic and the civil unrest caused by the killing of George Floyd led to a cascade of negative media stories about cities, often politically motivated. It seemed possible that the economic and demographic gains cities had achieved over the last few decades could be lost. In fact, there has been measurable population loss in larger cities caused by changing work/life patterns and changing public perceptions about the costs and benefits of urban living. Faced with these challenges, advocates for cities must make a vigorous case for cities and show how they aren't the cause of America's social, environmental, economic, and public health problems but, in fact, are the places where the solutions to those problems will be found. The 38 chapters in The Case for Cities draw on the expertise of contributors from the academic, professional, and civic sectors to explore the creative tension between the two great values on which the vigor of cities depends--that they should be "Cities of Choice" (places where people who have choice want to live) and "Cities of Justice" (places that welcome and support people with limited choices). The book's underlying perspective is that these two values are symbiotic and that promoting both is what leads to viable, sustainable urban resurgence. This book will be of keen interest to students and practitioners in urban planning, urban design, real estate, architecture, and landscape architecture and to urban advocates and civic leaders.
