That link I shared contradicts the sort of stuff you linked. Yes, there's a lot of stuff out there trying to posit that childless unmarried women are so happy but the actual proper, high sample size epidemiology suggests the opposite, from what I know:
One in five British women born in the 60s don’t have children – and the grief many of them feel has rarely been acknowledged. But now they, and men in the same position, are organising with others around the world to gain recognition and comfort

Also, I really, really, really need you and every guy and girl on this site to read this:
A lot of people on this site do not understand basic science and I've noticed that, unfortunately, with a lot of the sisters. So many of you like to post epidemiological, survey and generally correlative studies and then use them to make conclusions and back up whatever beliefs you have and it's incredibly irritating to watch cos it's nonsense.
You cannot and can never make
ANY conclusions using correlative studies. They don't "say" anything, abaayo. They at most create vague food for thought that should encourage someone to maybe do a clinical study and see why the correlations look the way they do. Are the eedos you're familiar with regretful about having kids cos they were in abusive, shitty relationships? Are there are other confounding factors? Would they feel the same with a loving, present and supportive husband and if they had ideal health themselves both mentally and physically? Too many confounding factors. You cannot look at any of this data and say
ANYTHING conclusive. Anyone who tells you otherwise is a crackpot.
Even what I did with my post was mostly just saying that it's
possible women do benefit from marriage and having kids but at the end of the day those correlations could be for totally different reasons. Maybe married women with kids just have a higher chance of having kids look after them when they're older and thus reducing the risk of accidental deaths and that's all that studies showing they live longer show. Funny hot take but you get; we don't know what the real reasons are so conclusively blaming being unmarried or not having kids or
anything is pseudoscience. And since no one can ever actually conduct clinical trials to prove or disprove any of this as you'd need to treat humans like lab-rats for generations it's all just speculation and always will be.
My two cents? Regardless of your marital status, if you maintain good social relations and cohesion, keep stress down and eat and exercise appropriately you should live a long and healthy life. There's no clinical studies backing that but there's plenty of historical and mechanistic data that does.
