“Falling birth rates and rising life expectancy are accelerating the ageing of the population, with potentially significant impact on Dutch pensions.”

 

What is the focus of the paper?

The paper examines how demographic uncertainty — particularly a decline in birth rates, migration patterns, and rising life expectancy — could affect Dutch pensions. The authors analyse historical trends and construct scenarios up to 2100 using UN projections. The topic is urgent given historically low fertility and a shrinking workforce in the Netherlands. The study assesses impacts on the old-age dependency ratio and the financial sustainability of both the public pension (AOW) and supplementary pensions. The scope covers the Netherlands and Europe, with emphasis on macroeconomic effects of ageing on growth, interest rates, and returns.

 

What are the key findings?

Under the central scenario, the old age dependency ratio rises from 30 percent in 2020 to about 45 percent by 2075 and remains high thereafter. Extreme scenarios — such as a fall in number of children to 0.7 per woman — push this figure to 85 percent by 2100. Immigration can soften population ageing in the short term, but fertility and mortality developments are the most important determinants for the long-run. Linking the public pension age to life expectancy (at age 65) tempers the increase in the old age dependency ratio but cannot tackle the consequences of a decline in the fertility rate. Age related public spending increases substantially, with long term care spending as an importantdriver of public spending. Macroeconomic empirical analysis shows that an increase in population ageing can reduce economic growth and real interest rates.

 

What are the implications?

  • The pension sector should anticipate lower economic growth, lower investment returns, and an ageing participant base.
  • Further population aging could lead to tensions within the European Union due to deteriorating public finances, potentially resulting in higher inflation and rising government burdens.
  • Scenario analysis is essential for pension providers to map out the uncertainty in demographic developments and the potential risks to pensions.
