An Analysis of the Distribution of Birthdays in a Calendar Year
- liotier 14y agoIn France when a person's exact birth date is unknown, a fictitious birth date is set on the 1st of January of the estimated or actual year of birth. I know a few African-born persons in that case. I expected to see that reflected in a slight bump in observed births on the 1st of January... But no such anomaly exists in the article's data...
