Making cities more dense always sparks resistance. Here’s how to overcome it. - Vox: Urban density, done well, has all kinds of benefits. On average, people who live in dense, walkable areas tend to be physically healthier, happier, and more productive. Local governments pay less in infrastructure costs to support urbanites than they to support suburbanites. Per-capita energy consumption is lower in dense areas, which is good for air pollution and climate change.
Plus, dense, walkable areas tend to be buzzy and culturally vibrant. There’s a reason they are often so expensive to live in — lots of people want to live there. Demand exceeds supply.
But creating a dense, walkable area almost always means increasing the density of a built environment that already exists. Especially in developed countries, they’re not building a lot of new cities. They’re working with existing ones. And cities built after the advent of the automobile were generally built around cars, which generally means low density.
