I frequently use data from PEW when I write. This organization offers a new page that will be helpful. This page summarizes the present state of adolescent online activity based on PEW’s repeated surveys.
A note near the top of the page says – (Note: This page will be updated whenever new data is available.)
If I understand this correctly, the idea is to offer the page as a location people like me can access from time to time for PEW’s current description of adolescent online activity.
