The infographic represents the number of residents of Matera (in Southern Italy) with the same surname. The number of people with matching surnames is illustrated by the size of the text and the digit written in red. The larger the font size, the higher the number of people sharing the same surname. The poster can be viewed in two ways: observation from afar whereby only the larger and most common surnames will be legible and close observation by immerging oneself in the literature only to discover a few surprises, such as the coexistence of foreign names alongside the more traditional. The infographic was designed using the Open Data of the City of Matera.
