Although research shows a general decline in religiosity in Western societies, religious transmission seems to be an under-researched phenomenon, especially in Italy. We do not know much about the dynamics of socialisation that take place in the family and the main factors that determine the success or failure of religious transmission from one generation to the next. Nevertheless, the family context represents the first agency of socialisation towards religion, from an early age, through experiences with parents, grandparents and relatives. On the other hand, in an era of religious diversification, migration is becoming increasingly important for national religious landscapes. However, the transmission of religion in foreign families and the impact of migration on family religiosity are still under-researched. This paper presents some research perspectives that have emerged from an extensive and ongoing study of the intergenerational transmission of religion using data from the Movimiento Misionero Mundial
