Has March 1 changed over time?
Annual U.S. birth totals changed across this window, so a raw daily count moves with the size of the year. The chart uses each year's share of that year's births instead, in births per 100,000. Averaged over the first five observed years it is 264.9 per 100,000; over the last five, 285.8 per 100,000 (+7.9%).

Source break: 1994–1999 counts come from the CDC/NCHS daily file and 2000–2014 from the Social Security Administration daily file. The overlapping years 2000–2003 are taken from the SSA file only, so each year is counted once. But the step at 2000 is a change of source as well as a change of year, and any comparison across it includes that change.
The weekday the date fell on, scheduling practice and recording practice are all inside these lines.
A generation earlier, in the separate daily file for 1969–1988, March 1 ranked #220 of 366 with 9,484 births per occurrence. The 1969–1988 calendar and what changed since.
March 1 in five countries
Countries are compared only over the matched years 2007–2014, which all five sources cover completely, and using births per occurrence so that leap day is handled the same way everywhere. Each country's records are counted on their own.
| Country | Rank of 366 | Index (100 = average day) | |
|---|---|---|---|
| United States | #276 | 96.5 | |
| England & Wales | #259 | 98.4 | |
| Denmark | #286 | 95.3 | |
| Metropolitan France | #296 | 96.9 | |
| Malaysia | #191 | 99.5 |
In the matched window the U.S. rank is #276; over the full 1994–2014 collection it is #176. The two numbers answer different questions and usually differ for two reasons at once: the window is eight years against twenty-one, and the metric is births per occurrence against the total across the whole period. Every figure on this page names its window and its metric. Full five-country study.

Sources, method and limits
Main ranking: 85,712,738 recorded U.S. births on 7,670 calendar dates, 1994–2014. CDC/NCHS daily counts for 1994–1999 and Social Security Administration daily counts for 2000–2014, as compiled by FiveThirtyEight and attributed under CC BY 4.0. The overlapping years 2000–2003 are counted once.
Ranks compare totals across the 366 observed month-and-day dates. February 29 occurred 5 times in this window; every other date occurred 21 times, so per-occurrence figures are used wherever seasonality is compared.
Every figure above comes from the administrative records named here, at the granularity those records publish: a day, a month or a year. Coverage and definitions differ between countries and eras, so two sources are combined only where their documentation states the windows are separate, and the page where that happens says so.
Full method, leap-day treatment and definitions.
