Pew Internet has posted the above presentation, given by Susannah Fox to the National Library of Medicine on July 8. Her message was startlingly clear: If your health content is not accessible on mobile devices, it is not available to some groups.
And, according to her thoughtful commentary (which was posted today), it's not available to a startlingly large group:
Fully 84% of 18-29 year-olds now go online wirelessly, compared with 69% of 30-49 year-olds, 49% of 50-64 year-olds, and 20% of adults age 65 and older.
I'm particularly struck by this stat: Twenty percent of wireless internet users go online exclusively on a cell phone.
That point draws on a Pew report on mobile access from last week. All of which prompts Fox to characterize this shift as being:
. . like watching the effects of erosion on a coastline: The information landscape is shifting and the changes are picking up speed. . . Now is the time to make changes to online services to account for both the popularity of mobile access and the way it is changing us as internet users.
