No. November 14 has more recorded births than most dates in these historical U.S. records. It ranks #134 of 366 dates by total births from 1994 through 2014. Rank #1 means most common.
November 14 had 237,247 births across 21 occurrences, or 11,297 births per occurrence. That is 0.277% of the 85,712,738-birth sample, or about 1 in 361 recorded births.
Within November, November 14 ranks sixth of 30 dates.
Five of its 21 occurrences fell on a Saturday or Sunday. The average across all dates is 6.0. Weekend days have fewer recorded births, so this calendar mix can raise its total. This comes from the calendar in these years, not from the date itself.
Does November 14 differ from nearby same-weekday dates?
It depends on which controls we use. In SSA 2000–2014, the primary comparison gives +2.4%. With only the 7-day controls, the result is -1.4%. With only the 14-day controls, it is +8.4%.
Because the sign changes, these results do not show clearly that November 14 has more or fewer births than nearby dates.
In the primary comparison, November 14 was above its controls in twelve years and below them in three.
Baseline ranks use historical U.S. CDC/NCHS and SSA records, 1994–2014. The percentage differences use SSA 2000–2014 alone. Each table row compares November 14 with controls from the same year.
| Comparison | Years | Control observations | Difference |
|---|---|---|---|
| 7 and 14 days, holidays excluded (primary) | 15 | 55 | +2.4% |
| 7 days only | 15 | 30 | -1.4% |
| 14 days only | 15 | 25 | +8.4% |
| 7 and 14 days, no holiday exclusions | 15 | 60 | +5.2% |
How were the comparison dates chosen?
The primary controls are October 31, November 7, November 21, and November 28 in the same year. Each is 7 or 14 days from November 14, so it falls on the same weekday.
In some years, a planned control falls on Thanksgiving Day or the Friday after it. We remove a Thanksgiving control under the standard observed federal holiday rules. The Friday after Thanksgiving is not a federal holiday, but this study also excludes it. The year keeps its other controls.
Without holiday exclusions, the result changes from +2.4% to +5.2%. Holiday controls usually have fewer births in these records, so including them makes November 14 look higher.
The primary and 14-day comparisons include October 31, which ranks
By five-year period, the primary differences are +2.2% for 2000–2004, +3.0% for 2005–2009, and +1.8% for 2010–2014.
To combine the years, we divide the summed target births by the summed annual control means. Then we subtract one and multiply by 100. The result is not an average of annual percentages.
Does the November 14 rank change over time?
Somewhat, but less than most dates. We ranked 365 recurring dates by SSA births in each five-year period. November 14 placed #119 in 2000–2004, #81 in 2005–2009, and #144 in 2010–2014. The three ranks span 63 places.
The median span for all 365 recurring dates is 159 places. This span is below that median.
Each period has one weekend occurrence of November 14, so the weekend mix does not explain the movement.
These ranks use raw birth counts. The ranking-stability study also compares annual shares and weekday-relative scores for every date.
Sources and limits
Baseline totals and ranks use FiveThirtyEight’s pinned U.S. birth files. We use CDC/NCHS for 1994–1999 and SSA for 2000–2014, so no year comes from both sources. Annual comparisons use SSA alone.
The source series have different administrative coverage. These records do not describe worldwide births, everyone alive today, or current birth rates.
The daily totals do not record delivery methods or scheduling decisions. Weekday matching does not remove every seasonal difference. Federal holiday rules identify calendar dates, not hospital schedules.
