The Lincoln Institute of Land Policy does this movement a great service with their Visualizing Density website, which provides extensive photographic evidence of the ugliness and monotony of sprawl alongside photos of appropriately dense, liveable neighbourhoods. It begins:
Sprawl is bad. Density is good. Americans need to stop spreading out and live closer together. Well… that’s the theory, anyway. But, as anyone who has tried to build compact development recently will tell you, if there’s one thing Americans hate more than sprawl, it’s density… One reason people reject density is that they don’t know much about it-what it looks like, how to build it, or whether it’s something they can call home. We have very rational ways of measuring density, but our perception of it is anything but rational.
