The percentage of U.S. online adults using Twitter remained about the same as of February as it did in May last year, but the percentage using it on a typical day nearly doubled between May, 2011 and February and quadrupled since late 2010, according to results of a Pew Internet & American Life Project study.
Some 15% of online adults were using Twitter as of February, with 8% doing so on a typical day. The first observation is in-line with Pew’s findings of May, 2011, when 13% were using Twitter. But the average percentage of U.S. adults using Twitter on a typical day has increased 400% since late 2010, when just 2% of Twitter users used the offering on a typical day.
Pew posits that increased smartphone usage might account for some of the big uptick in Twitter use among U.S. adults.
The Pew report was based on research conducted by Princeton Survey Research Associates International. Researchers conducted telephone interviews in English and Spanish with 2,253 adults. The margin of error due to sampling is plus or minus 2.7%.
Some 72.2 million Americans accessed social networking sites or blogs via mobile devices in August, an annual increase of 37%, according to a comScore MobiLens service report.
