Here's a structured summary of the Pew Research report on cell phone usage by American adults:

Key Findings Overview

Cell Phone Ownership:
- 82% of American adults (18+) own a cell phone, Blackberry, iPhone, or similar device.
- Younger adults (18-29), minorities (Black/African American, Hispanic), and higher-income/educated individuals are more likely to own cell phones.
- Usage has been steady since 2009.
Texting vs. Calling:
- Adults send an average of 10 texts/day, compared to teens' 50 texts/day.
- Heavy texters (50+ texts/day) are also heavy voice callers, while light texters (1-10 texts/day) are light callers.
- Only 72% of adults text daily, up from 65% in Sept 2009.
User Demographics:
- Age: 90% of 18-29-year-olds own a cell phone; 57% of those 65+.
- Race/Ethnicity: Black (87%) and Hispanic (87%) cell owners exceed white (80%).
- Income/Education: Higher income ($75K+) and college-educated individuals are more likely to use cell phones.
Cell Phone Attitudes:
- 9% of cell owners feel irritated by interruptions (calls/texts). Concern over rude cell checking is shared by 86%.
- Positive views: 91% feel safer due to cell phones; 88% use them to arrange plans.
- Negative views: Users spend an average 2.5 hours daily (inc. interruptions and boredom-fighting).
Teens vs. Adults:
Teens text more intensely (50 vs. 10 texts/day) and are more likely to sleep with phones (84% vs. 65% of adults).
Function Usage:
- Calling/Texting: Similar for on-the-go tasks; text messaging grows as internet alternative for those with limited/zero internet access.
Spam & Disruptions:
- 57% of phone owners receive spam texts. Study shows lower-income/minority users report more interruptions.
