Sources, method and limits

Source for 2014: Social Security Administration daily births for the United States, as compiled by FiveThirtyEight (CC BY 4.0). The 2000–2003 overlap between the two files is taken from the SSA file only. Weekday is taken from the record’s calendar date. Ranks within a year compare single days.

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.
