Sources, method and limits

Source: Office for National Statistics, daily live births by date of occurrence, Table 12 of the births release of September 8, 2026, Open Government Licence v3.0. Births occurring in England and Wales, including to mothers resident elsewhere, as registered by the release date. 697,852 births over 365 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.
