Sources, method and limits

Source: INSEE, T79jnais, daily births in metropolitan France, open licence of the publisher. Metropolitan France only; the whole-of-France detail file behind the 2025 page is a separate series. 767,816 births over 366 days; the weekday of each day is taken from the calendar date. One year, one country, one series.

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.
