More people are tweeting than ever before.
Twitter has been rapidly expanding, with the latest figures showing over 300 million registered accounts.
Twitter adoption is especially high among the African-American and Latino populations. Twenty-five percent of African-Americans and 19 percent of Latinos use Twitter, compared to 9 percent of whites.
Pew notes further that one in ten African-Americans visit Twitter daily, twice the rate for Latinos and four times that for whites.
By age, 18- to 29-year-olds are still the most likely group to use Twitter, with 18 percent on the site. Use among those aged 25 to 44 is growing quickly as well. Since 2010, the number of people aged 30 to 49 using Twitter has doubled from 7 percent to 14 percent.
For those aged from 25 to 34, the percentage of people on Twitter grew from 9 percent to 19 percent. Yet for the youngest of the adult population, aged 18 to 24, Twitter adoption stayed stable.
