Have you ever wondered how many of Twitter’s users are women? Or men? What about Facebook, MySpace, Digg, LinkedIn, and other sites in the social media sphere?

We have tracked down this information for a number of social network sites (19 of them). All the major ones have been included, like Facebook, MySpace and Twitter and also some of the most popular social news sites; Digg, Reddit and Slashdot.

Full list of sites in this mini study:

Facebook, LinkedIn, MySpace, Twitter, Slashdot, Reddit, Digg, Delicious, StumbleUpon, FriendFeed, Last.fm, Friendster, LiveJournal, Hi5, Imeem, Ning, Xanga, Classmates.com, Bebo.

To determine the ratio between male and female users on these sites we used site demographics data for the United States gathered from Google’s Ad Planner service.

Before we move on to the chart, here are a few quick observations based on the results we got.

• 84% (16 out of 19) of the sites have more female than male users.
• The social news sites Digg, Reddit and Slashdot have significantly more male users than female. The standout here is Slashdot which takes male geekdom to new heights with 82% male users.
