With support from the Rockefeller Foundation, the Urban Institute explored trends and differences in economic exclusion in cities across high-income countries, as well as strategies that cities have put in place to combat it. We found that city leaders are responding with well-known solutions and innovative new approaches, and they are rethinking the ways they govern around issues of exclusion. This brief defines economic exclusion and discusses city-level trends across high-income countries. It also describes how information technologies are opening up new possibilities for creating more inclusive and open urban economies.
