Because of their youth, and since the U.S. young are more diverse in race and ethnicity than the online U.S. population as a whole, Twitter users are also a more varied racial and ethnic mix than the country overall. For the same reasons of age, they are somewhat less affluent. According to PIP, 17% of users in Internet households earning less than $30,000 annually use Twitter or other status update platforms, while only 10% of users in households earning $75,000 or more a year do so.
