Common Sense Census: Media Use by Kids Age 0 to 8, 2017 Summary

Core Content Overview

This report presents the findings of the third nationally representative survey conducted by Common Sense on media use by children aged 0 to 8 in the U.S. The survey included over 1,400 parents, capturing trends in media consumption over the past six years (2011, 2013, and 2017). The study focuses on the time spent on various media activities, the devices used, and how these behaviors differ by demographic factors such as income, education, and race/ethnicity. It also examines parental attitudes toward children's media use and the emergence of new technologies in young children's lives.
