Sciences thrive in cities. With two-thirds of the global population projected to live in urban areas by 2050, cities will become even more distinctly the domain of knowledge and innovation. Nature Index 2017 Science Cities explores the high-quality research being produced by 10 cities in the natural sciences. We chose them for their strong scientific credentials, metropolitan flair and global connections.
Cities are magnets for people, resources and infrastructure — essential components for the generation of new ideas. We present here other factors that make for an ideal knowledge city. The elements might seem obvious, but there's no magic formula for how to combine them. Data analysis by Aaron Ballagh, data visualization by Daniel Ormella.
