Findings should be considered draft findings, lightly checked at best. This check of the report was done as a test to check the robustness and usefulness of the Toolbox.

Teen Screen Time Context Report: "Nearly 9 Hours" Claim Analysis

"Teens average nearly 9 hours of non-school screen time each day."

Summary: This statement is factually accurate based on 2021 Common Sense Media data showing teens averaged 8 hours 39 minutes of daily entertainment screen time. Notably, this figure represents pandemic-era peak usage (a 17% increase from 2019 levels). While initial studies have suggested screen time remained elevated post-pandemic, there is a significant data gap in comprehensive screen time measurements for 2023-2024, leaving the current status somewhat uncertain.
