Is there a link to the 100 pages so that the rest of us can be forewarned by your testimony?

Possibly, it will take me quite awhile to fully redact it of PII.

I hadn't considered that. Hope it works out for you. That was a brief moment of trauma reading your story.

Tl;Dr: ~30% of births are C-section, and hospitals prefer early morning operations.

Just had baby Dr wanted to do it at 7:00 and the hospital required us to be there at 5:00am. Dr showed up half an hour late. The reason he scheduled for then was so he could still do office hours. His office closes at noon. Don't like the guy.

Hospitals and the medical profession have a lot of work, and for efficiency they stack the work up. A rule of thumb whenever dealing with a hospital is that everything will be massively later than you expect. It's a good idea to set your expectations ahead of time so that a bit of a wait does not take you by surprise. For a hospital procedure, half an hour late is pretty much right on time.

Congrats on the baby!

You have to remember that you are not the only patient in the hospital. A Caesarean section requires a lot of setup including OR, anesthesiologist, ensuring adequate care for the newborn, etc. Any of these can cause a delay. Of course there is other cases triaged by urgency like crash sections. It would make no sense to show up to the OR 30 minutes before you can begin operating. An elective Caesarean section will always get bumped for emergencies.

This is a good example of how in the real world, everything is correlated with everything. Understanding this principle, I would expect uneven birth times and birth dates. I may not be able to guess what will cause it to be uneven (though in this particular case I would have gotten pretty close), or by how much it will deviate from uniformly random (I would have gotten this wrong to the low side), but it's sure to be something.

To put it another way intuitively, in a complicated world with so many things impacting so many other things, to have a totally uniformly random birth times or dates would essentially require some active force to smooth the times and dates out, because it is beyond implausible that absolutely nothing would have an impact. From diurnal hormone cycles, traffic cycles, preferences about surgery times, and probably another dozen things you could think of that could impact the times, it is implausible to expect that they would all be completely wrong or that they would all precisely cancel.

Uniform randomness is a very convenient mathematical fiction for making Statistics 101 problems easy enough for students to do. This is a necessary thing and it's hard to imagine how to avoid it. But in reality almost nothing is ever truly uniformly random. There's always something out there that's going to correlate it with something. It is a sad side effect of this need to simplify problems enough to be tractable by students that we end up teaching that uniform randomness is somehow the "default" distribution and the others are exceptions or something.

The answer is scheduled C-sections and if you haven't read it, Atul Gawande's 2006 New Yorker article on why they've become so common is good read: https://www.newyorker.com/magazine/2006/10/09/the-score After watching The Business of Being Born , Gawande's article was really helpful in understanding why things are done the way they are.

That’s correct, and scheduled C-Sections are also the reason Christmas is the rarest birthday.

An unfortunate side effect of the US hospital business is that you have a large number of customers and have to push people through the system as quickly as you can. That's probably why there has been such an increase in birth centers for mothers who want the time to go through labor naturally.

Nah, in completely socialized systems doctors and nurses also usually want to have weekends and evenings off, hospitals aren't staffed as well as during business hours, and people try to limit the workload on their colleagues remaining on duty.

The contrast to "the US hospital business" is not necessarily "socialized systems". A better contrast is, as the original commenter pointed out, birthing centers (or home births). A contrast to a hospital OBGYN in the US is a certified nurse midwife.

How labor and delivery doctors treat women is criminal. A hospital should not be a butcher shop.

You mean a generally-recommended-as-medically-necessary-only procedure that would result in far more complications were it not performed?

And anyway, people get surgeries all the time, how is this any different?

Not the only reason. Time of year also matters a lot for more "natural" reasons. IIRC mid-September is the peak and it goes down on either side, so late December is going to be pretty low anyways. Then you add in C-Sections and it drops to the absolute bottom.
