Dollar Street — walk the world's homes by income (opens destination in a new tab)

I fell down the best rabbit hole this afternoon. Dollar Street lines up 400+ real homes from around the world along one imaginary street — poorest on the left, richest on the right — and lets you wander through kitchens, bedrooms, and front doors by income level instead of country. It's photos-as-data, strangely addictive, and it quietly shatters a few stereotypes along the way.
