NPR data journalist Matt Stiles recently posted this informative infographic of the most common birth dates in the United States.

It was constructed using data compiled by Harvery Kennedy School professor of public policy Amitabh Chandra, and later published in the New York Times. Chandra's table relies exclusively on birth date figures from 1973 to 1999.

A couple of fun facts: The most popular birth date is September 16th; the least popular date is split between February 29th (no duh) and December 25th (there can be only one?). As for the prevalency of September birth dates — well, let's just say it takes a lot of alcohol to get through the holiday season in one piece.

You can check out Andy Kriebel's interactive version of the same infographic over here.
