Courrier des statistiques N4 - 2020

Continuing with its exploration of the professions and methods associated with official statistics, this issue, N4, firstly addresses a practice that is not usually linked with this area: microsimulation (whether dynamic or static), and how it is used within an NSI or in ministerial departments. Two specific models are explained: TRAJECTOiRE, which looks at the pension system and Ines, which discusses social and fiscal policies. Four papers are then dedicated to benchmarks for statisticians: firstly in France, through the overhaul of the nomenclature of socio-professional categories, the SIRENE company register overhaul programme, and the update to the new master sample. Sweden’s experience is then discussed, which focusses on modelling statistical processes and the organisational impact of this, providing an external contribution that we are particularly pleased with. Finally, the issue rounds off with a panorama of the housing information system in France in its entirety.
