In short: Denmark reached six million inhabitants in April 2025, yet the country's natural population growth remains fragile. While immigration drives recent expansion, internal fertility trends are transforming, with immigrant women now recording lower average birth rates than those of Danish descent, marking a significant shift in the nation's long-term demographic landscape.

The composition of Denmark is defined by nuanced classifications from Statistics Denmark, which categorizes residents based on ancestry and country of origin. As of 2026, approximately 83.2 percent of the population is of Danish descent, while 16.8 percent—over one million people—are immigrants or their descendants. This group is further split into Western and non-Western backgrounds, with the latter accounting for nearly 65 percent of the migrant population. These figures are dynamic; for instance, the influx of Ukrainian citizens in 2022 accounted for over a quarter of all immigration that year.

Fertility rates provide a window into these changes. In 2022, the total fertility rate was 1.55 children per woman. Historically, non-Western immigrant women maintained higher birth rates, but recent data shows a reversal: women of Danish roots now average 1.78 children, slightly higher than the 1.76 average for immigrant women and 1.75 for their descendants. This shift is partly attributed to the large-scale arrival of Ukrainian refugees. Meanwhile, the average age for first-time parents continues to climb, reaching 29.8 years for mothers and 31.5 years for fathers in 2021.

Historical context also shapes the modern demographic map. A notable example is the German minority, or Nordschleswiger, residing in the border region. This community, numbering about 15,000, has roots in territory that shifted between Denmark and Germany. Following the 1864 conflict, the area was part of Germany until it returned to Denmark on June 15, 1920. This territorial change caused a sharp spike in migration statistics that year. Today, the Danish Realm includes diverse groups, such as 23,000 ethnic Faroese and 19,000 Greenlanders, all of whom hold Danish citizenship, reflecting the complex, layered identity of the modern Danish state.
