Interestingly enough, this advice is bordering outdated. In the US, recent estimates put children being born to unwed parents at around 40%.
This varies by race and income- for example, since 1990 the rates for white parents doubled from 15 to 28%, whereas on the other end of the spectrum the rate went from 63 to 69% for children of black parents. Breaking down by economic, education and other levels follow more or less similar trends- big jumps at the low end of the range, small jumps on the upper end.
Edit- another interesting tidbit, divorce rates are highest among those over 55; presumably, parents whose children are now adults are moving on, whereas younger parents simply aren't getting married in the first place.
It makes sense parents that don’t share the load equally drift apart. I see so many families where one parent gets all the hobbies and trips while the other gets to stay home or work on kids and Housework 24/7
