A new study from Pew Internet finds that the number of daily Twitter users among adults has doubled since May of last year, even though the overall percentage of Twitter users has only grown 2 percent since that time. The authors of the study attributed the increase to a rise in smartphone usage—smartphone owners are twice as likely as others to use Twitter on a typical day. Young adults have had the largest increase in smartphone usage, which perhaps explains why 18 to 24-year-old Internet users have undergone the largest increase in Twitter usage: about one third of them use Twitter, and those who use it on a daily basis have doubled.
Besides young adults, the study found that African Americans and those who live in and around urban areas were more likely to use Twitter compared to the general population. And what the study calls the “mobile difference” applies to groups beyond young adults: 25 to 34-year-olds, African Americans, and Latinos have higher rates of mobile Twitter usage. However, as Jeff Bercovici points out at Forbes, the study’s findings do not seem to agree with Twitter’s own usage numbers. Whether the numbers point to an overall stagnation or just a momentary slow-down remains to be seen.
