Anna Rosling Rönnlund has spent the last 15 years making global public data easier to understand and use. Trying to come up with an idea that would connect with people better than colorful charts, she started Dollar Street. The initiative had a team of photographers documenting over 264 homes in 50 countries. In each home, the photographer spent a day taking pictures of up to 135 objects, like the family's shoes, toothbrushes, or... children's toys.
