Dollar Street, from the GapMinder Foundation, uses a well-designed interface to help counter misconceptions about different income levels in the world.
Their main point is that people don’t uniformly live in “poor” or “rich” countries like most of us tend to think but that people actually share similar lifestyles, items that they own, and things they do and desire, when they have similar incomes, whether they live in Canada, China or Cambodia.
(Uhm, Canada is not actually one of the countries in their survey – a strange oversight.)
