The Destinie model has been developed and maintained at the French national statistical institute (INSEE) since the mid-1990s. A new version is progressively becoming operational and this paper presents the main options that have been retained for this new model. The main goals of this new version have been the improvement of consistency with official demographic projections, the incorporation of more complex labour market trajectories, and increasing portability and facility to use. The new model makes a complete separation between two components. The first component is a generator of demographic and employment biographies, whose results are then stored in two intermediate output files. The second component is a library of subroutines allowing an easy programming of pension projections based on these two output files resulting from the first stage.
