sci fi target audience

From looking at the sci fi genre i have discovered that the target audience is aimed at 15- 30 this is because from looking at most sci fi films and their age rating it tends to be rated 15 for most films. one other reason that the target audience is 15-30 is because sci fi films help escape reality so it takes away stress from stressful times allowing the viewer to be put in a whole different world that isn't his/her's but then it is also good to see the different possibilities and thoughts on the futuristic technology.
