Reddit is more popular among men than women and the young than the old, a Pew Research Center study confirmed today . The social network's strength is among (advertiser-friendly) 18-29 year old males. One surprising finding of the study is that five percent of women aged 30-49 say they use the network, which is the same proportion as younger women.

The social network's audience is evenly spread across income categories, and has a u-shaped distribution in education: those without a high school diploma and those who have at least an undergraduate degree are most likely to use Reddit.

Overall, six percent of the people surveyed said that they had ever used the service. In all likelihood, a substantial percentage of Reddit users are probably under 18, but that group was not included in the survey.
