Industrialised economies are experiencing a decline in mortality alongside low fertility rates - a situation that puts social security systems under severe pressure. Population ageing is associated not only with longer periods of pension claims but also smaller cohorts eventually entering the...

In this paper, a time series of UK annuity income rates (AR) based on historical interest rates but modern mortality rates (hence the term “semi-historical”) has been derived for both nominal and inflation-linked annuities. The errors associated with the calculated rates for nominal...

A new algorithm for clustering life course trajectories is presented and tested with large register data. Life courses are represented as sequences on a monthly timescale for the working-life with an age span from 16–65. A meaningful clustering result for this kind of data provides interesting...

The demographic transition is a phenomenon affecting many industrialized societies. These economies are experiencing a decline in mortality alongside low fertility rates - a situation that puts social security systems under severe pressure. To implement appropriate reform measures, adequate...

Population forecasts are crucial for many social, political and economic decisions. Official population projections rely in general on deterministic models which use different scenarios for future vital rates to indicate uncertainty. However, this technique shows substantial weak points such as...
