Innovation is the driver of economic growth in the global economy, and cities and metropolitan areas are the wellspring of innovation. But the benefits of innovation and the resources that support innovation do not always reach all corners of the metropolis, and this exacerbates economic and social divisions that hinder our economy and weaken our communities. We can bridge this gap by cultivating the creativity and entrepreneurial spirit of people who live in underserved communities and recognizing them alongside more traditional or obvious urban innovators. Who are the urban innovators, and how can we make sure that the resources in cities that promote innovation are available to all residents, wherever they live?
