Sources, method and limits

Source: Jabatan Pendaftaran Negara (National Registration Department), Malaysia, live births by date of birth, published by the Department of Statistics Malaysia on data.gov.my, CC BY 4.0. Births are counted by date of birth. Pages cover 2000 onward, because the earlier registration series shows artefacts described on the Malaysia page; the partial 2023 stays outside the rankings. 457,945 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.

Full method, leap-day treatment and definitions.
