How Many People Were Born The Same Day I Was?

// December 20th, 2011 // 5 Comments » // Information, Personal

I recently became 28, and started thinking to myself, what is the probability of meeting a random person that was born on my birth date.

Normally we would say that meeting someone that shares your same birthday has the probability of 1/365, which means that you have a 0.274% chance of meeting someone that shares your birthday.

However, in real life, peoples’ birthdays aren’t distributed equally. For example, I found a dataset online with 481040 birthdates for an insurance company. This dataset shows that Aug. 18 had the highest number of births, while Dec. 26 had the least number of births.

The chances of me meeting someone that shared my same birthdate became 0.266% which meant that my birthday had a lower number of births than the average. That also means that for every thousand people I meet, there are 2.6 that share my birth date.

Then I started thinking, what are the chances of me meeting someone that was born the same year I was born. Now we could just assume that the average lifespan of a human is 68 according to the World Health Organization, and say that my chances of meeting someone are 1/68. However, in real life that’s not the case. The number of births increase exponentially. According to this wikipedia entry:
“The population of the United States of America is exponentially increasing at an average rate of one and a half percent a year (1.5%). This means that the doubling time of the American population (depending on the yearly growth in population) is approximately 50 years.”
Plus the numbers of deaths per year are not the way they were a century ago. We have fewer wars now, and the number of deaths has also decreased due to advancements in medicine.

Back to the question, what are the chances of me meeting someone that was born the same year I was born? Recent stats show that there are 7 Billion humans on this earth. The year I was born had about 78 million births. According to the UN data, it was estimated that 105 die between birth and the age of 5 for every 1000 births during the year I was born. It is also estimated that there are about 50 deaths per 1000 people between the ages of 5 and 29 for various reasons for natural causes to wars (I’m not 29, but its close enough). So, we can say that around 850 per 1000 people born in the same year I was born are still alive today. That means 66.3 million of the 7 billion people on this earth were born the same year I was born.

So, the chances of me meeting a person born the same year I was born are 0.947%.

Finally, what are the chances of me meeting someone that was actually born on the same day I was born? If we take the probability of being born on the same day I was born, and apply that to the 66.3 million that were born the same year I was born. Then we would come to the result of having about 176280 people in the world that were born on the same day I was born and are still living today.

The chances of me meeting someone born on the same day I was born are 0.0025%.That means that there are only 25 people in every million, that were born on my exact birth date! So, given the population in Montreal of 1.6 million, there are only 40 people!
