What is your comment meant to convey, except the fact you believe that, despite the available data, childfree people must really be going to regret not having children?
They do not express desire to have children. They do not have children. They do not regret that, even as their peers deal with theirs. What reason could possibly there be to believe that they would suddenly start regretting their decision after 70?
If it comes down to the fact they "won't have anyone to take care of them in their old age", I posit that their situation is not going to be very different from that of many bechilded people (modulo any money the childfree people might have saved by not having to provide for another human being), which will - and should, if having a "free" caretaker in their old age played a part in it - regret their decision.
