   • Short-form video platforms like TikTok saw daily use increase to 14 minutes/day, up from 1 minute pre-pandemic.
   • Decline in reading time among older children (5-8 years old): falls to 52% daily reads vs. 64% in 2017.

5. Data on AI

   • 63% of parents view media as useful for learning, but 78% worry about attention-span issues and inappropriate content.

3. Research Methodology

• Primary data source: 1,578 U.S. parents surveyed digitally via a probability-based panel.
• Study conducted by Common Sense Media in August 2024.
• Margin of error: ~2.9% at a 95% confidence level.
• Comparative analysis with surveys from 2011, 2013, 2017, and 2020.

4. Key Data Tables

1. Average Daily Screen Media Use (Hours: Minutes):

   • 0-8 years old: ~2:27 (varies by age).

   • YouTube, TikTok, and games remain dominant.
   • Gaming time increased by ~15 minutes/year across age groups.

Conclusion

The study reveals persistent screen usage trends normalized during the pandemic, growing reliance on AI by children, and sharp socioeconomic disparities. While parents remain split between technological advantages versus harms, scientists and policymakers will need to continue examining this dynamic landscape.
