On January 1, 2026, 6,025,603 people lived in Denmark, and Statistics Denmark counts every one of them by day and month of birth, wherever in the world they were born. Spread over the dates that come round every year, that is about 16,466 people per birthday, or one resident in 366. The fullest ordinary date is March 21 with 18,312 people and the emptiest every-year date is December 25 with 12,742; February 29 has 3,929, about a quarter of an ordinary date, as expected for a date that comes once in four years. This is a count of people alive and resident today, a stock; the Denmark birth ranking is the flow.
January 1 and July 1 are administrative
The two largest counts, January 1 (24,673 people) and July 1 (19,851), are administrative dates. Statistics Denmark states that when a person born abroad is registered with the day of birth unknown, an administrative date is assigned, and those assignments fall on January 1 and July 1. Both dates stay in every table on this page, labelled and as published. Several other first-of-month dates are also high in the list below (March 1, October 1, June 1, May 1). The publisher documents only January 1 and July 1 as administrative, so only those two are labelled.
Every date of the year
People living in Denmark by birthday, index (100 = average every-year date), January 1, 2026
Every calendar date in order as one line, residents with that birthday indexed to the average every-year date, with the two administrative dates, the fullest ordinary date and leap day marked.
The spikes are the two administrative dates; the late-December dip is shared with the birth series; the spring plateau belongs to the residents alone.
The ten fullest birthdays among people living in Denmark, January 1, 2026
Every date coloured by the reveal’s six tiers applied to the resident counts, fullest to emptiest, with its rank of 366 in the corner. The exact count for any date is on the line chart above and on that date’s own page.
People alive today were born across a century, so the resident calendar reflects every birth year since the 1920s and everyone who has moved in or out, while the birth series counts only 2007–2025. Indexed to their own averages, the two peak in different months: residents are fullest in April and March, while births per day in 2007–2025 are highest in July; both are lowest in December. This page records the difference.

Residents per every-year date and births per day, by month, indexed
Source: Statistics Denmark, table FOLK3, population on January 1, 2026 by day and month of birth, under the publisher’s open data terms. The 366 counts on this page sum to the published total of 6,025,603 exactly. The table counts everyone resident on the snapshot date, including people born outside Denmark; it is a stock of people.
Statistics Denmark documents that administrative birthday assignments for people born abroad inflate January 1 and July 1. Those two dates are shown as published and marked wherever they appear. A large or small count on any date says how many residents have that birthday.
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.
