If you aren’t one of the 24% of US and UK Internet users playing social games at least weekly, you may have seen the traces of those players and their FarmVille or Scrabble exploits in your Facebook newsfeed. PopCap Games, maker of several popular titles, explored the demographics of the group in its “2010 Social Gaming Research” report.

More than one-half of players are female, and the average US player is 48 years old. Relatively few US weekly gamers are under 30, while nearly one-half are over 50.
