What age groups are SNSD members in charge of?

SNSD is once again on fire due to the extreme attention that they are getting from their new song, Run Devil Run. They have fans all over the nation and there isn't one who hasn't heard of them. Their fans are mixed into various age groups, and apparently, each member is in charge of one specific group. On the March 20th episode of�Star Golden Bell, Sooyoung, Jessica, Yuri, and Hyoyeon were guests. The members were asked, "You�must have�different fans from every age; What is the age group that the majority of fans are in�for each member?" Sooyoung answered, "I am in charge of the uncle fans." She then explained, "At fansigning events, the fans say things such as "I like Yuri!"", "Jessica noona! My brother likes you!", "Hyoyeon noona, our sister really likes you." and "Sooyoung noona, our dad loves you!" Are the fans spot-on with the definition?
