Spotting patterns in birthdays


from

The basic one of "When it's cold outside people stay in and have sex" is fairly obvious.

But laying things out like this, you can see the faint horizontal line that shows that nobody wants to give birth on the 13th.

And that medical staff _really_ don't want to work at Christmas. Or Independence Day.

Depressingly high evidence of elective Caesarians - look at Valentine's Day as well as the holiday periods.

32.8% is the total CS rate, not the ELCS rate, (which for some reason I can't track down). Most CSs are "emergencies" following issues in labour and therefore unaffected by date preferences except insofaras they are more common following induction.

(Although I was offered a choice of birth date during my EMCS, but that was because it was 11:59 pm at the time.)

Also hadn't noticed til now how the "holiday period" light days are followed by very dark ones - my daughter's December 30th birthday is obviously a popular "choice" for people keen to avoid actual holidays clashing with birthdays. And to think I achieved that purely by accident.

That's partly why Valentine's Day is so dark - it's a combination of "ah, Valentine's Day would be sweet" and all the pent up demand from the 13th the day before.

Yep; I was due on Feb 12th, but as my mum had been told she'd need a C-section, she chose the 14th "so the postman would think she was popular".

Not just ELCS, inductions would lead to that pattern as well.

Ah, 'course, yes.
