Although research shows a general decrease in religiosity in Western societies, religious transmission still seems to be a poorly studied 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. Yet, the family context represents the first agency of socialisation to religion, from an early age, through experiences with parents, grandparents and relatives. On the other hand, in the age of religious diversification, the migration factor is becoming increasingly crucial for national religious landscapes. Nevertheless, religious transmission in foreign families and the impact of migration on family religiosity are still little studied. This contribution presents some research perspectives that have emerged from a wide-ranging survey, still in progress, on intergenerational transmission of religion in Catholic, Muslim and Orthodox families in Italy.
