A new population projection from national agency Statistics Denmark predicts 431,000 people of the age of 80 in Denmark in 2030.
That will increase to 617,000 by 2050, around 10 percent of the population.
Today, Denmark has around 282,000 over-80s in its population, which is around 5 percent of the population.
A large increase in the number of elderly persons is expected to present Denmark’s social welfare system with economic challenges, with larger numbers likely to need care and practical help.
In its report, Statistics Denmark writes that the “greatest (population) growth going forward is expected to take place amongst the oldest age groups”.
Other age groups are not expected to greatly change their proportion of the population during the period covered by the projection, the agency writes.
The overall population is expected to grow by 0.4 percent by 2028. After that, growth will plateau, giving a growth of 0.12 percent in 2050. It is then forecast to increase again, reaching 0.2 percent in 2060.
Major factors affecting the population size – birth rates, death rates and immigration – are all predicted to vary at different times throughout the period.
But Statistics Denmark writes that it expects a deficit in the number of births between 2044 and 2053.
The 2021 projection does not take into account the potential long-term impact of the Covid-19 pandemic on the population. That is because “no sufficient basis of knowledge and experience is yet available,” the statistics bureau writes.
However, the agency noted that the biggest impact of the pandemic on population size in 2020 was its restrictive effect on immigration and emigration.
