What demographic do ABC soap operas attract?

I am not into soap opera nor do I know people who watch "soap opera" but I am curious.

I heard back in the early 2010s shows on ABC like "Once Upon A Time" had viewerships past 10 million viewers in America alone.

I was under the impression that the average viewer of an ABC show are people from the suburbs in their 30s that thought HBO was too "graphic" for them. Is that just a preconceived notion or is there some truth to that?

Back in 2015 there was this show called "Astronaut Wives Club".

And it got more than 5 million US viewers on it's premiere episode and dropped to little below 4 million by it's last episode.

Later that year Syfy's shiny new space opera "The Expanse" premiered to a little more than 1 million viewers.


For a space adventure to appeal to a wide audience would it have to be either "Star Wars" or an astronaut soap opera like Apple TV's "For All Mankind" which has loads of soap opera combined with exciting space sequences?
