An Extension of the Conventional TFR



The period-based total fertility rate is probably the most commonly used single measure of a population’s fertility level, but it has the disadvantage that it only controls for the population’s age distribution and not for any other subdividing feature, such as the parity distribution, ethnic composition, or educational attainment. This may lead the TFR to change because the population composition changes, even when the underlying fertility remains constant in each population sub-group. In the present contribution, we use elementary event-history methods to show how one can easily control the TFR against a change in the population’s distribution across any selected subdivision. We use the data of the Romanian Gender and Generations Survey of 2005 to illustrate how this can be done.

Une extension de l'indicateur conjoncturel de fécondité


L’indicateur conjoncturel de fécondité (ICF) est probablement l’indicateur unique le plus utilisé pour mesurer le niveau de fécondité d’une population, mais il présente l’inconvénient de ne contrôler que la distribution par âge de la population sans contrôler d’autres éléments, telles que la distribution par parité, par composition ethnique ou par niveau d’instruction. L’ICF peut alors changer si la composition de la population évolue, même si la fécondité demeure constante dans chaque sous-groupe de population. Dans cet article, nous utilisons des méthodes élémentaires d’analyse biographique pour montrer qu’il est possible de calculer l’indicateur conjoncturel de fécondité en contrôlant pour un changement dans la distribution de la population, quel que soit le sous-groupe envisagé. Les données du volet roumain de l’enquête Générations et genre réalisé en 2005 sont utilisées pour illustrer cette méthode.
