The non-medical policies implemented by many countries to “flatten the curve” during the COVID-19 outbreak has people stranded in their homes and some, out of their homes unable to return due to the disruptions in the mobility network. The availability of rich datasets (in our case, Facebook) has made it possible to study the mobility dynamics and spatial distribution of people during lockdown in Italy.

Our interpretation is an effort to look deeper, describing the movements occurred during lockdown, including the territorial differences. We observe that, initially, tourists left the country and later Italians abroad managed to return, thereby, stabilising the population. With regards to internal mobility, the earliest affected regions see higher number of stationary users in the initial days of the outbreak while this is less significant for the central/southern regions until the decree for the official lockdown on the 9^th of March, 2020, due 2 days later. Just before lockdown, there was not a significant exodus of people from the North to the rest of the country, instead, relocation of people between cities and their urban belts, but not towards remote areas. This will be elaborated in conclusions shedding light on possible changes in future cities.

许多国家/地区在COVID-19爆发期间实施了旨在“平缓曲线”的非医疗政策，使人们滞留在其房屋中，有些人由于出行网络的中断而无法返回家园。丰富的数据集（在我们的示例中为Facebook）的可用性使研究意大利锁定期间人员的流动性动态和空间分布成为可能。

我们的解释是加倍努力，描述锁定期间发生的运动，包括领土差异。我们观察到，最初，游客离开了该国，后来，意大利人设法返回了国外，从而稳定了人口。关于内部流动性，最早的受灾地区在疫情爆发的最初几天看到固定用户的数量增加，而对于中部/南部地区而言，直到第9^号官方禁令发布之前，固定用户的数量才有所减少。将于2020年3月发布，截止日期为2天。在封锁之前，从北部到全国其他地区没有大量的人外流，而是在城市和城市地带之间迁移了人们，但没有向偏远地区迁移。结论中将详细阐述这一点，以阐明未来城市的可能变化。
