Historical dataset showing Denmark population density by year from 1961 to 2022.

Denmark has, by far, the highest population density of the Nordic countries. This is related to the fact that it is the smallest Nordic country in terms of land area. Meanwhile, Iceland, which has the smallest population of the five countries, also has the lowest population density. As the total population increased in all five countries over the past decade, the population density also increased.

Population density of Denmark went up by 0.79% from 146.4 people per sq. km in 2021 to 147.6 people per sq. km in 2022. Since the 0.38% improve in 2012, population density jumped by 5.57% in 2022. Population density is midyear population divided by land area in square kilometers.

Over the past decade, the Danish population gradually grew older. While there were around 230,000 inhabitants aged 80 years or older in 2014, this group counted over 320,000 people at the beginning of 2023. The largest age group, however, were Danes between 20 and 39 years of age, counting over 1.55 million people that year. Growing population The Danish population has constantly grown since 2000, almost reaching six million in 2024. This is explained by a higher number of people born than deceasing, and a higher number of immigrants than emigrants. In 2023, however, more people deceased than babies born. Eastern Europeans make up largest immigrant group The over 600,000 inhabitants in Denmark with a foreign citizenship underline the increasing role migrants play in Danish society. Many of these are people migrating to Denmark for work, such as many Poles, who make up the largest immigrant group ahead of Ukrainians. Many of the Ukrainians are refugees fleeing the Russia-Ukraine war that broke out in 2022.

About this dataset

Context

The dataset tabulates the Denmark population by age cohorts (Children: Under 18 years; Working population: 18-64 years; Senior population: 65 years or more). It lists the population in each age cohort group along with its percentage relative to the total population of Denmark. The dataset can be utilized to understand the population distribution across children, working population and senior population for dependency ratio, housing requirements, ageing, migration patterns etc.

Key observations

The largest age group was 18 to 64 years with a poulation of 2,036 (64.82% of the total population). Source: U.S. Census Bureau American Community Survey (ACS) 2019-2023 5-Year Estimates.
