Cell phones in school
"In a study of 625 teens 12% can have their phones all day in every class, 62% can have their phone but not in all classes, 24% go to schools with no phone policies, and the remaining 2% don’t go to school" (Lenhart).
Cell phone use
"Today 46% of American adults say they could not live without their cell phones. 15 years ago only 28.3% of people even owned a cell phone" (Lenhart).
