Do these counts explain the July 4 gap?
No. These birth records do not say why a delivery happened on July 4, July 5, or any other date. Weekday patterns also affect daily birth counts, and July 4 landed on different weekdays across the 21 years.
Our fixed-holiday study compares July 4 with nearby dates on the same weekday, using the SSA records from 2000 through 2014. That study asks a different question from this month ranking. Neither comparison establishes a cause.
How to read the July rankings
The July rank compares 31 dates; the overall rank compares 366. Both sort total recorded births from highest to lowest. Each July date occurred 21 times in this period, so dividing totals by occurrences leaves their order unchanged. Birth share uses recorded births across all months as its denominator.
Select July 4 and July 7 in the comparison above to see their count gap, or pick two other July dates.
Sources and limits
We calculated these rankings from daily U.S. birth records compiled by FiveThirtyEight. We use CDC/NCHS records for 1994 through 1999 and SSA records for 2000 through 2014, excluding the overlapping CDC years. The sources have different administrative coverage. These historical counts do not describe worldwide births, current births, or how many living people have a July birthday. The methodology explains the source selection and rankings.
