Any theories as to the cause then?

  Flynn effect

  Freedom from being forced to reproduce in recent/modern times for women, and the fact that a lot of women now have a lot of choices (such as going career focused). Not to mention the fact that a lot of younger people would prefer to have financial security "setup" first, before embarking on the journey of child raising (but unfortunately, this takes a lot of time, and fraught with uncertainty).

  It's entirely because people now have a choice of whether or not to have kids and most people are choosing not to for completely valid reasons.

  As children, humans are receiving a torrent of new information all the time. For hundreds of thousands of years, the torrent slows as the human becomes an adolescent, puberty kicks off, and then they have children as the product of the latest new sensation. All that is upended, now. Not only are people continuing to have an available torrent of information into their twenties, but now it is possible to just never stop, so the transition to the next stage of life doesn't happen for more and more, and we just stay (functionally) children into the thirties, forties, or later, after which it's too late for more than half of us. Not sure how seriously I take this. :)
