John Knodel, « Espacement des naissances et planification familiale : une critique de la méthode Dupâquier-Lachiver », Annales, ID : 10.3406/ahess.1981.282756
In an influential article published in Annales, just over a decade ago, Dupaquier and Lachiver proposed a technique for detecting birth control based on family reconstitution data. Their measure focusses on 'intervals' and was seen as an alternative to the measures proposed by Henry which focus on 'stopping' behaviour. The Dupaquier-Lachiver approach suffers from the main problems. It confounds the effects of birth spacing patterns with attempts to terminate childbearing and it is sensitive to the underlying level of marital fertility thus being incapable of distinguishing deliberate attempts at birth control from non- volitional factors which contribute to the determination of the overall fertility level. These problems are demonstrated with data from several German village populations.
