If you have ever wondered how many people share the same date as you for your birthday, there is a chart that was made to show you. The chart was devised by Matt Stiles, a data journalist with National Public Radio.

According to the map, September 16th is the most common birth date among Americans between 14 and 40. More Americans are born in September and July and share their birth date with a greater number of people.

The least common birth date is February 29th, which comes only once every four years.  The second least common is December 25th, followed by January 1st. For some reason the 13th of every month seemed to have fewer births.

Take a look at the chart and see how many people share your birth date.
