This report, dated May 7, 2012, from the Pew Research Center's Internet & American Life Project, examines the use of cell phones for obtaining just-in-time information through mobile connections. The survey was conducted from March 15 to April 3, 2012, among 2,254 adults aged 18 and older, with a focus on cell phone usage.

Key Findings

• Widespread Use of Phones for Real-Time Queries: Approximately 70% of all cell phone owners and 86% of smartphone owners used their phones in the past 30 days for at least one just-in-time activity. These activities included coordinating gatherings, solving unexpected problems, deciding on business visits, or finding emergency help.
• Common Activities: The percentage of users performing specific activities ranged from 19% to 88%, with navigation features used by 65% of smartphone owners.
• Demographic Differences: Usage was higher among younger adults (18-29 years: 88%), men, parents of children, higher-income households, and more educated individuals. African-American users were more likely to access traffic or transit information, while white users favored coordinating gatherings.

Methodology and Scope

The survey had a margin of error of 2-3 percentage points for key statistics. These findings underscore the growing reliance on mobile devices for immediate information access, driving a "real-time information seeker" culture.
