This study accounts for the heterogeneous consequences of the Covid-19 pandemic on fertility plans and behaviours, by focusing on the motivations for suspended pre-Covid fertility plans and on those for new fertility plans that arose during the pandemic. We rely on unique data collected with a repeated cross-sectional survey conducted in April/May 2021 and October/November 2021 on a sample of young Italians (aged 18-34). We estimate a set of multinomial and logit models to examine some correlates of fertility plans and behaviours. Then, we provide a more qualitative analysis of the reasons behind the resulting patterns of associations. Changes in fertility plans and behaviours from pre-COVID intentions clearly show that the economic recession burdens unequally individuals and their opportunities to cope with obstacles to both work and family involvement. At the same time, those who started to plan childbirth during the pandemic, frequently cite as important motivations the increased opportunities to enjoy the family life, the more balanced work and family involvement, the higher share of domestic tasks in the couple, and the improved relationship quality. Our results suggest the need for exploring also positive channels through which the Covid-19 crisis had provided opportunities for planning new births.
