The Business Insider provides an Edison report on Twitter demographics. It’s quite interesting.
One surprising finding: black people are overrepresented on Twitter: “black people represent 25% of Twitter users, roughly twice their share of the population in general.” BI has a separate article that speculates as to some reasons why:
Black people (and Hispanics) are much more likely to access the Internet from mobile devices. Twitter is well-suited to mobile use, and its users are more engaged with the mobile Internet than the general population by a wide margin.
More black than white celebrities are active Twitter users; Shaquille O’Neal, Oprah, 50 Cent, and P Diddy are all among the most followed accounts on Twitter. That’s great publicity for Twitter, and could be helping Twitter become more mainstream among black people.
