The COVID-19 pandemic has had a significant impact on various aspects of daily life, including reproductive behaviour. However, it is important to note that the impact of the pandemic on fertility is multifaceted and varies between and within countries and regions. This study explores the association between COVID-19 lockdowns, and exposure to death, on the birth outcomes in Italy, with a specific focus on Bergamo. Bergamo is an interesting case study as it was one of the most impacted city by the virus in the Western world. Preliminary results show that during the months of lockdown and high mortality, the number of conceptions decreases, and, conversely, during periods of reopening and stabilization of deaths the number of conceptions increases. Our results seem to corroborate the argument that the perception of uncertainty has an important impact on fertility dynamics, especially during a pandemic (and in general during catastrophic events).
