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. We analyse data from the Longitudinal register on reproductive histories from 1999 to 2017 (ISTAT). Results show significantly higher values of SRB for third births among Indian and Chinese communities when the first and second births are girls. A skewed SRB is also present among Indian babies born after a female firstborn. A more detailed analysis of SRBs for immigrants from China and India, by the sex of the previous children and inter-birth interval between second and third birth, did not indicate significant changes in SRB when the inter-birth interval is longer. Our study provides evidence for policymaking. However, further research is needed to address the causes of sex selection among immigrant communities. Efforts to alter gender norms and reduce son preference within communities are required to tackle gender discrimination against second-generation girls.
