Les différentiels sociaux de fécondité durant le baby-boom en Suisse

In this paper we want to explore the social differentials in the dynamics of the baby boom. The latter marked the trend of fertility in Switzerland beginning in the 1930s all the way to the 1950s. For this objective we rely on a large survey carried out in 2011/12 among more than 4000 elderly individuals living in Switzerland. This survey resulted in an impressively rich database since it also includes the parents of the baby boomers. Moreover, it offers information regarding the background of each individual, on accumulated human and social capitals and on family, residential and professional life trajectories. Furthermore, it also includes vast data concerning all of their children. After a description of the demographic trends, we performed two analyses focusing on:
First, the final number of offsprings
Second, the crucial intergenesic intervals from birth 2 to 3 and from birth 3 to 4.
Our ambition is to assess the social homogeneity or the social differentials during the baby boom in order to contribute to a better understanding of this phenomenon.
