How Rare Is Your Birthday?

How Rare is Your Birthday?

By Ella 

Have you ever wondered if you share the same birthday with many people around the world? Or how common your date of birth is? It turns out that some birthdays are actually more common than you thought! Keep reading to find out :)

The data set you will see below is according to studies done by the Center for Disease Control and Prevention’s National Center for Health Statistics, and the U.S. births data for births between 2000 to 2014 came from the Social Security Administration.

“The deeper the blue, the more people with that birth date. The deeper red, the less birth dates. It is worth noting that the deepest red is for months with no 31st day.” 

Interestingly, it’s not days that are more common, but months! 9 out of 10 of the most common birthdays are in September, but August is the most frequent birth month in the United States! An average of 361,709 August babies are born each year in the US. Tuesday is the most common day of the week to be born on. What did you think it was? Did you know that the highest percentage of births occur at 8 am and noon? I was born around 12:45 pm, so I guess my birth time is pretty common. 

However, the ratio of sexes at birth is 1.05 males per 1 female! If you are born in February, that is the least common birth month, with an average of 316,891 births every year. The 13th of any month is also one of the least common days, due to superstitions around the day. 

We’ve talked about months and averages, but let’s get to the fun part! Here are the 10 most popular birthdays in the US:

1. September 9th

2. September 19th

3. September 12th

4. September 17th

5. September 10th

6. July 7th

7. September 20th

8. September 15th

9. September 16th

10. September 18th

Like stated before, September isn’t the most common birth month. But, it is one of the busiest months for delivering babies. Something I found interesting was that the 10 least popular birthdays (below) were most often in the later months/the winter and the fall!

1. December 25th

2. January 1st

3. December 24th

4. July 4th

5. January 2nd
