Be Fruitful and Multiply! 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.
The probability that a person does not have the same birthday as another person is 364 divided by 365 because there are 364 days that are not a person's birthday. This means that any two people have a 364/365, or 99.726027 percent, chance of not matching birthdays.
December 25 (Christmas Day) is the least common birthday, while January 1 (New Year's Day) is the second least common. December 24 (Christmas Eve) also makes the list as the 3rd least common birthday while July 4 (Independence Day) is the 4th least common birthday.
Yes, you share your big day with millions of people. Getting a little more specific, there are about 885,000 Americans with the same birthday as you. In the most populous country in the world, China, you have about 3.8 million birthday buddies.
Quintuplets occur naturally in 1 in 55,000,000 births. The first quintuplets known to survive infancy were the identical female Canadian Dionne Quintuplets, born in 1934.
8 percent. Four people (lets call them ABCD) have a 1/91 chance, but there are 6 possible combinations (AB AC AD BD BC CD) so the probability becomes 1/91 + 6/365…and so on. You can see how it isn't quite as easy as just x/365!
Strictly speaking, there's no proper word for that situation. However, it is usual in the English-speaking world to call people who share the same birthday as "birthday twins." Less frequently "Irish twins," especially in the sense of same day and month but one year apart.
What is a Golden Birthday? Your golden birthday is when the date of your birth coincides with your age. For example, if you were born on October 8, your golden birthday took place when you turned 8. If you were born on December 21, your golden birthday took place when you turned 21.
The only verified example of a family producing five single children with coincident birthdays is that of Catherine (1952), Carol (1953), Charles (1956), Claudia (1961) and Cecilia (1966), born to Carolyn and Ralph Cummins (USA) all on 20 February.
According to the World Bank, for every 1,000 people in the world, an average of 7.748 people will die each year and 19.349 will be born. That's a ratio of about 2.5 births for every death.

And if you were born in the 20th century, you'll likely relate to these Photos That Kids Born After 2000 Will Never Understand.
The chance that the third is born on that day as well is 1/365, and assuming that there is no common factor linking those birthdates then the total chance of the three birthdays coinciding is 1/ (365 x 365 ) = 1 in 133000, or 7.5 in 1,000,000.
1 in 133,000 – the odds of both parents and child sharing the same birthday.
For example, the hour with the most births per week, 8 to 9 A.M. on Mondays, is mostly driven by C-sections. C-sections are up by 3.7 times average whereas natural births are just above average and inductions actually slightly less common than average during that hour.
A huge population in the Indian sub-continent celebrate their birthdays on two different days – one the official one, and one on the day they were actually born.
August has the number one ranking in average number of births. About 21 million Americans, or nine percent of the population, have birthdays in August. July and September follow closely behind, with 8.8 percent of birthdays, and February is last, with 7 percent.
August is the overall most popular month for birthdays, which makes sense, considering a late August birthday means December conception.
You know the ones I am talking about — the ones that end in a zero. The ones that make you happy when you are young, happy that you are getting older, can do more, be more. The zero birthdays as you get older that make you stop and think about your future, your life, your family, your mortality.
The crude birth rate is 18.2 births per 1,000 population or 267 births globally per minute or 4.5 births every second (2018 estimate).
Octuplets are a set of eight offspring born at one birth. An individual that is part of such a set is called an octuplet.
The girls are technically not twins. Identical twins occur when one egg splits into two and non-identical, or fraternal, twins occur when two eggs are released and fertilised at the same time. So even though Miss Spence's babies were born on the same day, they are not twins as they were conceived three weeks apart.
A diamond jubilee celebrates the 60th anniversary of a significant event related to a person (e.g. accession to the throne or wedding, among others) or the 60th anniversary of an institution's founding.
