Design with the Other 90%: Cities," the second in a series of themed exhibitions by Cooper-Hewitt that demonstrate how design can address the world's most critical issues, opens October 15 at the United Nations and runs through January 9, 2012. Organized by Cynthia E. Smith, the museum's curator of socially responsible design, the exhibition will feature more than 60 projects from 22 countries around the globe.

The exhibition will explore design solutions to the challenges created by rapid urban growth in informal settlements, commonly referred to as slums. Close to 1 billion people live in informal settlements, and that population is projected to swell to 2 billion people by 2030. This accelerated urban expansion will take place primarily in developing and emerging economies in an increasingly climate-challenged world. Projects and products at every scale will be included, with a focus on designs that are informed by end users: alternative housing design, methods and materials; low-cost clean water; accessible education initiatives; sanitation and solid-waste management; transportation solutions; innovative systems and infrastructure; and urban design and planning.
