Is that a bad thing?
Studies show that the happiest people are married men and single women. But studies also show that women who are childless are not so by choice.
Some didn't find the right partner, some found it too late to have kids and so on.
There's just a lot to consider and I think such stats are not for the entire generation everywhere because where I live almost everyone is married by 30 and has kids by 40 max. And even 30 is considered too late for marriage.
