Interestingly, the most and least common birthdays align with actual birth data, revealing that while the holidays are a popular time to conceive, they aren’t typically a time when many babies are born.
Understanding your due date involves knowing much more than when you can anticipate your child’s birth. It will impact everything from the practicalities of your labor to the time of year your child will celebrate his or her birthday.
Wondering if your soon-to-be-born child will share a birthday with the majority of their classmates during the most popular birthday month? Or perhaps they will be born on the least frequent day of the year for newborns to make their grand debut. Due to a viral blog article by Matt Stiles of The Daily Viz, you can determine that.
Maybe the best aspect of Stile’s viral post is that the data is presented in a colorful heat map, making it easier to interpret the numbers. The stunning exhibition demonstrates that September is a busy month for births.
The data also reveals that, as entertaining as it may be to determine how uncommon your birthday is (or is not), the approach has a little flaw: the busiest days for births are not significantly busier than the rarer days. According to the author, the busiest days on the calendar have 12,000 births, while the least busy days have approximately 6,500 births, with 11,000 being the median.
Still, it is enjoyable to visit. Interested to see where your child’s birthday is projected to fall? Below are the most common birthdays in the United States.
The Most Common Month of Birth
Utilizing actual birth data (covering 20 years of U.S. births) collected by FiveThirtyEight from the National Center for Health Statistics and Social Security Administration, Stiles determined that September is the most popular month for giving birth in the United States. In fact, nine of the top ten birthing days happen between September 9 and September 20.
The obvious question is why?
Many couples are conceiving in December and around the holidays, according to Whitney Casares, M.D., M.P.H., F.A.A.P., author of The New Baby Blueprint: Caring for You and Your Baby. It makes sense that they may be more likely to become pregnant during the festive seasons.
According to a study published in Obstetrics and Gynecology, couples may have more success conceiving during the winter season due to higher-quality sperm in the winter than in the summer. “They also hypothesized that changes in the amount of daylight could make an ovum’s environment more favorable for sperm,” she explains. “More research is required to comprehend this intriguing occurrence.
