Skewed Sex Ratios at Birth in Italian Migrant Populations: Evidence from a Longitudinal Register 1999-2017.

Many studies in different settings have suggested that migrants from countries with skewed sex ratios at birth tend to adjust the sex of their offspring to ensure the birth of at least one male child. Enlarging the scope of existing research, the present study explores the phenomenon by studying the sex ratio at birth and sex selection at birth among migrants in Italy, focussing on birth order and the sex of the previous child. We perform a descriptive analysis of SRB by birth order (first, second and third), sex of the previous children, inter-birth interval and citizenship of the child.
