The number of adults using Twitter every day has doubled since 2011, according to a new survey.
Eight percent of adult Internet users said they log on to Twitter every day, up from the 4% who said the same last year, according to the Pew Research Center, which conducted the survey.
That number was even higher for young adults. One in five Internet users ages 18 to 24 are using the website each day, and nearly one-third of all users that age are on Twitter.
The reason for the increase in daily usage is likely because of the rise of smartphones, the survey suggests.
"Those ages 18-24 are not just the fastest growing group when it comes to Twitter adoption over the last year," the survey reads. "They also experienced the largest increase in smartphone ownership of any demographic group over the same time period."
