Compare Denmark with another country
Where it stands
In 2025 Denmark has 6,009,169 people, which is 0.073% of the 8.19 billion counted across the 217 countries and areas on this site. That puts it 114th by population, behind Singapore and ahead of Lebanon.
Since 1960
In 1960 the figure was 4,579,603. Since then the population has grown 1.31×, an average of 0.42% a year upward. It has not yet doubled since then.
The projection puts the peak in 2043 at 6,108,692, after which it declines. By 2050 the projected total is 6,090,718, 1.4% above the 2025 figure.
The ranking in 2050
In 2050 the projected rank is 119th, down 5 places from 114th. Rankings move when other countries grow faster or slower, not only when Denmark changes.
People and land
Denmark covers 40,000 km² of land, so 2025 density is 150 people per km² — 77th most crowded of 216 places with an area figure. At that density a square 10 km on a side holds about 15,023 people.
The fertility rate was 1.47 births per woman in 2024, below the roughly 2.1 needed to keep a population steady without migration; life expectancy at birth was 82.3 years (2024); 15.6% of people were under 15 and 21.1% were 65 or older (2025); 89% of the population lived in cities. These shape the curve above: a young population keeps growing after fertility falls, an old one starts shrinking sooner.
Its nearest neighbours in the ranking are Singapore just above, with 6.11 million (1.02× as many), and Lebanon just below, with 5.85 million (1.03× as many as Lebanon has).
