Numbers game: According to a heat map created by Matt Stiles, a data journalist with the National Public Radio, September 16 is the single most common birthday for Americans between the ages of 14 and 40

Stiles created his map using data drawn from a chart that had been posted on the New York Times site in 2006, which ranked every day of the year based on how many babies were born in the U.S. on that day between 1973 and 1999.

The darker colors on the heat map appearing on the site The Daily Viz indicate the date has a lower-numbered birthday rank and the lighter colors a higher-numbered birthday rank.

For example, in the month of June, the majority of the days are ranked in the 100th and 200th range, with the most common birthday being June 30, ranked 75th on the chart.
