Thriller Target audience

I feel that the thriller target audience is probably 15-35its for people into intrigue and mystery with a tint of a twist. Its for people who like to try and work things out for themselves but sometimes never quite gets there .A person who never gives up trying and will always give it a shot on working out what in happening, yet still loves the element of surprise. But it also depends on the sub genre of the Thriller, action thrillers for example are mainly for young people where as political thrillers are maybe set for an older audience.
