Since i have decided this week to turn my birthday into a weeklong celebration, my mother and i over lunch discussed what would be the distribution of birthdays across the days of the year. I figured that because of certain dates(valentines day)/old wives tales(blackouts) that some days would have higher numbers of conception, therefore peaking birthdays. Well, after much discussion over what sample size(10% of 6.6 billion would be a sample size of about 660 million people worldwide), how to obtain the data and other finer points, i found one of the most interesting papers ive ever read. Someone did research on the topic, however, the data is specific to college students, not a worldwide sample.
Strangely enough, the most popular birthday in america is oct 5th, exactly 9 mos after new years eve. The least popular is may 22nd.
Check out the paper here. Its pretty interesting.
Data Sample
Btw, only my mother and i would have a conversation over lunch about sample sizes, data manipulation and other forms of number dorkery.
