Information graphics should be designed for the target group they address. This is common good practice for any graphic design. The series of infographics shown below provide the rare opportunity to see the same informational content designed for four different target audiences: the age groups of preschool children, school children, teenagers, and adults.
These information graphics show instructions for thoroughly washing one’s hands. They are available as stickers to be stuck on mirrors in toilets. They are provided by the German Federal Office of Health Education (Bundeszentrale für Gesundheitliche Aufklärung) for download here, under a creative commons license.
Some of the choices made by the designer(s) can be a matter of debate. In any case the underlying principle is demonstrated very well: Text, fonts, imagery, and colors are chosen to make the information graphic suitable for the given audience.
Based on this principle, how could a corresponding information graphic for the elderly be designed?
