Using data collected in a Barracuda Networks survey and analysis from Razorfish, Digital Surgeons, an online marketing agency, has created an infographic that compares Facebook users to Twitter users. As should be expected with services that are exploding in popularity like these two are, the data is a bit outdated: Facebook now boasts more than 550 million users, and Twitter 190 million. Still, the side-by-side comparison of social demographics makes accessible a lot of information valuable to marketing and advertising agencies.

As you can see, Facebook and Twitter users are pretty similar: A majority of users are outside of the United States for both, about one third login using mobile devices, and the gender breakdown is about the same. But there are some key differences, too: Facebook users tend to be younger, Twitter users are more educated, and Facebook users are more likely to login everyday even if they don't update their statuses with the same frequency.

As both companies start to focus more of their efforts on bringing in revenue, the biggest differences on this infographic will be the areas most parsed. Twitter users are less interested in following brands than Facebook users, but those Twitter users who do follow a brand are more likely to purchase a product. How will that influence the direction these two giants move in?
