Note that "social games" are web-based games like Mafia Wars and FarmVille that you play on social networks like Facebook, not Xbox 360 action games like Gears of War or Halo — young males still dominate that branch of the gaming hobby.
The survey found that 55% of social gamers are female and 45% are male. Females are more avid gamers, too; 38% of females said they play multiple times a day, but just 29% males said the same. Women are more likely to play with people they know (68% vs. 56% for males), and men are more likely to play with strangers (41% vs. 33%) than women are.
There were more insights in the survey beyond gender. Facebook is the most popular destination for online games, with 83% of respondents saying they have played games there. Twenty-eight percent have purchased in-game currency with real-world money. The average gamer has played six social games, and more than 50% of gamers started playing a game because a friend recommended it or because they saw a friend playing it in a news feed or other social stream.
