Birthdays

In today’s post we’s like to deviate a bit from the usual ultrasound pregnancy scan content to talk about birthdays! As the world is celebrating the birth of 2021 we decided to look at some stats on the ONS website. Ever wondered how common is your birthday?

We looked at some stats from the ONS and about average daily births in England and Wales from 1995 to 2014. It’s not a big surprise that the least common birthdays coincide with national holidays: 26th Dec, 25th Dec and 1st Jan are the least popular birthdays according to ONS data (in this order.)

The curious thing is that the most popular birthday period comes towards the end of September, and in particular September 26th being the most common birthday (followed by September 25th and 24th.) September 26th is 39 weeks and 2 days after Christmas, which is approximately 9 months… Hmmmm, looks like a lot of babies are being made right now during the festive season!

City Ultrasound was born on 12th of April which is the 305th out of 366 in the list. How popular is your birthday? Visit the ONS website to find out!
