Why is September the most popular birth month?

September is a month full of back to school shopping, planning for labor day and…having babies? If you’re expecting a baby in September, you’ve got company! Studies have shown that nine out of ten of the most common American birthdays fall in the month of September. Let’s take a deep dive to understand why so many babies are born in September.

September's baby boom

For the last two decades, September has been the busiest month for births in America. Nine months before September is December, which is most likely the month of conception for September babies. December is statistically proven as the most popular time that Americans get pregnant. While holidays might be one explanation for this trend, it’s also likely that taking time off of work plays a factor. With less time spent in the office, couples find more time to spend in the bedroom.

What is the most common birthday? 

September 9th is the most popular birthday in the US, followed by September 19th. Another explanation for the popularity of September birthdays is elective births and induction. Many people who have the option to choose when they give birth avoid holidays because  hospitals tend to be understaffed around the busiest holiday seasons. This explains why the least common birth dates are Christmas Eve, Christmas, and New Years Day.

The dates of conception for the nine out of ten top birthdays that fall in September are between December 17th and December 28th. It’s hard to determine exactly which day of conception is the most popular, as babies are not always conceived the day that you have sex. In fact, sperm can live in your fallopian tubes for up to 5 days while waiting for you to ovulate. Additionally, no two pregnancies are the same and babies that were conceived on the same day will most likely still have different birthdays.

What is the most popular zodiac sign?

While the zodiac signs associated with September are Libra and Virgo, these signs don’t take the cake for the most popular. 9.6% of the US population are Scorpios. Those born between October 22nd and November 21st are Scorpios, the most common zodiac sign. Next are Virgos at 9.4% of the population, followed by Geminis at 9.3%. The least common horoscope sign is Aquarius, accounting for 6.3% of the US population and falling on birth dates between January 19th and February 19th.
