Demographic ageing in Denmark in the twentieth century

"In the twentieth century the Danish population has, in demographic terms, aged considerably, the proportion of the population aged 60 years and over having increased from 9.8 to 19.6 per cent. The expected population development for the remainder of this century suggests that this ageing will continue until about 1990, after which the effects of previous fertility experience will reduce the proportions of elderly. Although the proportion of elderly begins to decrease after 1990, the number of persons aged 85+ by the year 2000 is expected to increase substantially."
