Gapminder have just launched a new version of their DOLLAR STREET tool, which enables comparisons between countries. At a time when we are moving away from the idea of developed and developing countries, it's useful to have a visual tool of the range of data to show comparisons between places.
The tool has a range of stories, and is based on over 30 000 photos, taken of over 200 families in 40 locations. Families can be ranked within the world as a whole, or smaller areas, and by indicators including toilets and teeth.
It provides an alternative visual way of showing diversity in quality of life.
