Birthday Popularity — An Interactive Map

Clearly, I am not the only person out there who thinks birthdays are interesting. People with a lot more talent than I have for visualization and processing data have put together a cool heat map demonstrating the popularity of different birth dates.

Any loyal readers of this blog know already that September birthdays are the top-ranked for popularity, but on his “digital sketchpad for data stories” site, Matt Stiles provides an interactive way to see where your big day lands in comparison to others in the world.

Birthday Popularity Ranked

To get the results, two decades of American birthdays, from 1994 – 2014, were averaged by month and day. There’s even an estimated conception date, for those who don’t shudder to think about that reality about their own parents.

It’s interesting to see that only one of the dates in the top 10 is outside of the month of September. Apparently October 14th is a particularly appealing day for parents to get busy!

While we’re at it though, let’s take a moment to reconsider the fact that you share your birthday with an estimated 11,000 people in America alone! That’s the median number of births per day.

A couple of other things I learned? Selfishly I of course looked up my own birthday. Turns out it is more common as a date of conception (netting a June 29 birthday at 111th), than it is a date of birth (115th, with a date of conception estimated at January 13 — no, Dad, if you’re reading this, I don’t need further detail about that critical January so many years ago…some things can be kept private between you and Mom, OK?).

I may not be a fan of data and statistics if I have to do any of the calculations. But I do love it when someone makes it so easy for me to sort through and find out cool stuff. Enjoy!
