Les espérances de vie appliquées à des statuts spécifiques : historique des indicateurs et des méthodes de calcul
Cambois (Emmanuelle), Robin? (Jean-Marie), Brouard (Nicolas).- Life expectancies applied to specific statuses: a history of the indicators and the methods of calculation Indicators of life expectancy applied to specific statuses, such as the state of health or professional status, were introduced at the end of the 1930s and are currently the object of renewed interest. Because they relate mortality to different domains (health, professional activity) applied life expectancies reflect simultaneously the demographic dynamic of a population and the evolution of its functional characteristics. This article presents a historical survey of the methods of calculation and the indicators they have produced. These methods are organized into three groups: single-decrement life table methods, multiple-decrement life table methods, and increment-decrement life table methods. Each of these possesses its particular characteristics, strengths and weaknesses. The choice of method will depend on the aims pursued and the data that is available. Data from cohort surveys - so-called 'flow' information - can be used to construct multiple-decrement tables or increment-decrement tables, which are accurate but based on a complicated methodology. Data from cross-sectional surveys - so-called 'stock' information - necessitate the use of single decrement tables, based on a methodology that is straightforward and robust but which introduces a bias. Choosing between these methods involves weighing the indicator's ease of application against the error size involved, and according to the aims of the study.
