I think some of the numbers are skewed because of induced births. Hospitals won’t schedule an induced birth on Christmas day, if they can help it.
Ah yeah - I found myself staring at the 2nd half of December a bit puzzled, but you’re absolutely on to it.
People party around end of year. Babies get born 9 months later.
People really working hard to have kids on Valentine’s day.
I’m guessing this data is from one hemisphere (the northern?)
My guess is just the US, because of the low birth rate on 4th of July.
I would have thought Feb 29 would be an extra-dark level of blue
are there absolute numbers? it would be interesting to know how big is the deviation.
I spent far too long looking at this graph thinking that blue was male and pink was female and drawing the wrong conclusions
Same here. I wondered how that was even possible before discovering my Lemmy client had cropped out the legend. Not a fan of this coloring scheme, especially having white as the median value.
Looks off. Isn’t it more the days of conception rather birthday? It’s rather lucky that they are so many babies on feb14, exactly on Valentine days
peak just before and after Christmas would indicate that it’s day of birth, since hospitals work with reduced capacity on these days and induced births or c-sections will not happen then unless it’s an emergency.
why so many births are on 14.02. is a mystery to me.
Best guess seems to be choice of day to induce labor within a given window. A lot of people, if given a window of Feb 7th through 21st or something, will choose the 14th for Valentine’s Day
Astrology chart
Jan 1st and Dec 25th both less common than Feb 29th? Sounds unrealistic.
Other users have pointed it out: this data set likely includes induced births and c-sections, neither of which would be scheduled on a holiday.
You can also see a dip around 4 July, so this data is probably from the USA
