Religion and Fertility : The French Connection

The dataset "Enquête Mode de Vie des Français" is the first opportunity to measure the impact of religion and religiosity on individual fertility behaviors in France. Indeed, the French laws make it very difficult to collect data on the individual's religious variables. With Poisson regressions, I show that religiosity is the sole religious variable which significantly influences fertility. To have been raised in a religious family and to be a believer do not matter either. The estimated fertility of a woman assisting offices every week is 24% higher that the expected fertility of a woman who never assist to offices. Culture is not investigated only through the impact of religion on fertility. Indeed, I explore the influence of parental fertility on the respondent's own fertility and the transmission of "Family Ties" among generations. I find that these two channels are as important as religious variables to explain fertility. Among the conclusions of usual family, economics, I find that male income has a positive impact on female fertility whereas the female income has a negative impact. The women's education negatively influences fertility in the sense that the least educated women have more children than others.
