A Pew Internet survey in 2012 examined several demographic variables of users of social networking sites including sex, age, race, education and income. Of the 1,802 users surveyed, 846 were men and 525 of them used social networking sites. Among the 956 women in the survey, 679 of them used social networking sites. Is there good evidence that the proportion of Internet users who use social networking sites is different for men and women.
