And the Most Common Birthday in the U.S. Is …

What do movie actors Adam Sandler and Hugh Grant, jazz singer Michael Bublé, Russian literary giant Leo Tolstoy, and Colonel Sanders, the founder of KFC, have in common?

Hint, it’s not a Nobel Prize for Literature, a Golden Globe, a Grammy Award, a trademark goatee, or a “finger-lickin’ good” bucket of chicken. Instead, they were all born on September 9, the most common birth date in the U.S.

Baby Boom

According to real birth data compiled from 20 years of American births, September is the most popular month to give birth to a child in America – and December, the most popular time to make one.

With nine of the top 10 days to give birth falling between September 9 and September 20, one may wonder why the birth month is so common. Here are some theories:

  • Those who get to choose their child’s birthday due to induced and elective births tend to stay away from the hospital during understaffed holiday periods and may plan their birth date around the start of the school year.
  • Several of the most common birth dates in September correspond with average conception periods around the holidays, where couples likely have more time to spend together.
  • Some studies within the scientific community suggest that our bodies may actually be biologically disposed to winter conceptions.

While you may not be feeling that special if you were born in September, the actual differences in birth numbers between common and less common birthdays are often within just a few thousand babies. For example, September 10, the fifth most common birthday of the year, has an average birth rate of 12,143 babies. Meanwhile, April 20, the 328th most common birthday, has an average birth rate of 10,714 newborns. Surprisingly, the least common birthdays fall on Christmas Eve, Christmas Day and New Year’s Day, with Thanksgiving and Independence Day also ranking low on the list.

Time to Celebrate – but Watch out!

Statistically, there’s a pretty good chance that someone reading this article will soon be celebrating their birthday. And while you should be getting ready to party, you should also be on the lookout for fraudsters attempting to ruin your big day.

It’s a well-known fact that cybercriminals can use your birth date as a piece of the puzzle to capture your identity and commit identity theft – which becomes a lot easier when it’s being advertised all over social media. It’s also important for employers to safeguard their organization from fraudsters who may use this information to break into corporate accounts.

While sharing your birthday with a lot of people could be a good or bad thing depending on how much undivided attention you enjoy – you’re in great company! Not only can you plan a joint party with Michelle Williams, Afrojack, Cam from Modern Family, four people I went to high school with on Facebook and a handful of YouTube stars that I’m too old to know anything about, but there will be more people ringing in your birthday than any other day of the year! And that’s pretty cool.

Used EV Growth Signals a New Phase of Consumer Purchasing Behavior

The electric vehicle (EV) revolution isn’t slowing down, it’s changing lanes. While recent conversations have seemingly focused on softening demand for new EVs, the used segment has been gaining momentum. According to Experian Automotive’s 2025 EV Year in Review Report, new retail individual EV registrations fell 35.9% year-over-year. Meanwhile, the used retail individual EV registrations grew 25.4% from a year ago. As affordability and growing model availability reshapes consumer behavior, buyers are increasingly turning to pre-owned EVs, which has shown an interesting market divergence that is redefining how consumers are adopting this segment and what it can mean for automakers, dealers, and the overall industry. Key players behind rising used EV demand Notably, Tesla accounted for over half (60.5%) of used retail individual EV registrations in 2025, followed by Chevrolet at 6.4% and Nissan (5.5%). Diving a bit deeper, Tesla made up the top three models of the used individual registrations last year, with the Model 3 coming in at 27.2%, Model Y at 21.7%, and Model S (6.6%). The Chevrolet Bolt EV followed at 4.8% and the Nissan Leaf was at 4%. Tesla’s position as the leading make in the used EV market is a natural extension of its long-standing dominance in new EV sales. The brand’s leadership over the years created a large fleet of vehicles that are now entering the pre-owned market. What the used EV boom means for automotive professionals The growing demand for used EVs can present more opportunities for automotive professionals. Dealers that provide a healthy supply of pre-owned EVs can increase accessibility and play a role in adoption for consumers who are actively looking to purchase, while marketers can emphasize value and ownership benefits. As the market continues to evolve, automotive professionals who understand and respond to these changing dynamics will be best positioned to capitalize on the expanding pool of used EV shoppers.
