They Live the Longest
While October babies have the highest risk of disease among all birth months, they don't let that stop them from living very long lives. According to a 2011 study of over 1,500 centenarians (or people that live to be 100), babies born between September and November live the longest.
Additionally, the golden birthday is considered especially lucky and special since it only occurs once in a lifetime. If you're over the age of 31 and are feeling sad you may have missed your golden birthday, have no fear! Turning the age of your birth year is considered a platinum birthday.
Being a December baby can sometimes feel like a downer because birthdays can get forgotten in the holiday rush. But the truth is that people born in December are impossible to overlook.

The UN estimates that around 385,000 babies are born each day around the world (140 million a year). This number will remain relatively stable in the 50 years from 2020 to 2070. From 2070 to 2100, the number will decline to around 356,000 (130 million a year).
Since the world population is estimated at over seven and a half billion,1 you should, in theory, share your birthday with over 20 million people (~20,438,356).

The crude birth rate is 18.2 births per 1000 population or 267 births globally per minute or 4.5 births every second (2018 estimate). The current world population is growing by about 215000 people every day. It is projected to hit 8 billion by 2023 9 billion by 2037 and 10 billion by 2057.
In general, humans tend to give birth to slightly more boys than girls, and in the U.S. more boys tend to be born during the early spring and summer months than the autumn and winter. The reasons for that seasonality are not well-understood.
One study estimated a woman can have around 15 pregnancies in a lifetime. And depending on how many babies she births for each pregnancy, she'd probably have around 15-30 children. But the "most prolific mother ever," according to Guinness World Records, was Mrs. Feodor Vassilyev in 19th century Russia.
