The data comes from an infographic in the Digital Reader, and that infographic's data comes from Student Monitor.
I recommend our students always check the sources of an infographic to determine its authority before they look at it. I pronounce this one a keeper.
The chart is geared for college students and adults, especially the price comparison reference to Grey Goose. The inclusion of this particular data would be a great opening for a discussion with my students about choosing data to match their target audience.
Thanks, Allison, for this creative commons gem that you helped create. I'll be sharing it freely.
