Washington – Significantly more U.S. adults are now using microblogging service Twitter compared with late last year, according to a new report from the Pew Research Center Internet & American Life project.
As of May, 13% of online adults said they were using the service, up from 8% in November 2010.
More than half (54%) said they access Twitter from their mobile devices.
The data also shows that African-Americans are significantly more likely than whites to be Twitter users.
One in 10 African-American Internet users now visit Twitter on a typical day — double the rate for Latinos and nearly four times the rate for whites.
