It’s true that in many cities, air quality is better now than it was decades ago. But urban air quality is still a health risk in far too many places. Premature death from air pollution is about 50 percent more common in cities than in rural areas. On days with higher air pollution, stock returns are lower, and students perform worse on exams.
