As of May 2010, 82% of American adults own a cell phone, with 72% regularly texting, but adults text significantly less than teens, averaging 10 texts per day compared to 50 for teens. Cell phones serve primarily for voice calling, with adults making around 5 calls per day, and ownership varies across demographics such as race, age, and parental status, with minority groups typically using their phones more. Despite some frustrations, many adults find their phones crucial for safety and connectivity, often keeping them nearby even when sleeping.
