"Neighborhoods with a mix of older and newer buildings are more diverse in age, race and income. They have “hidden density”—more people and businesses per square foot than areas with just new buildings. They are more walkable and have more creative jobs. They have more new and women- and minority-owned businesses. And they show more activity on evenings and weekends."
