COVID-19危机极大地改变了整个国家的流动性。基于位置的社交网络数据可用于研究危机期间的流动性。意大利的封锁导致当地和全国的流动性几乎为零。然而，没有观察到人口大规模流离失所。城市人口不是向偏远地区，而是大多向城市带转移。在COVID-19爆发期间，许多国家实施的“拉平曲线”的非医疗政策使人们滞留在家中，部分人因交通网络中断而无法返回家园。丰富的数据集（在我们的例子中，Facebook）的可用性使得研究意大利封锁期间人员的流动动态和空间分布成为可能。我们的解释是为了更深入地了解，描述封锁期间发生的运动，包括领土差异。我们观察到，最初，游客离开了这个国家，后来国外的意大利人设法返回，从而稳定了人口。在内部流动性方面，最早受影响的地区在疫情爆发的最初几天看到更多的固定用户，而在中部/南部地区，这一点不太重要，直到2020年3月9日的官方封锁法令，两天后到期。就在封锁之前，并没有大量人口从北方逃往该国其他地区，相反，人们在城市及其城市带之间重新安置，但没有迁往偏远地区。这将在结论中详细阐述，阐明未来城市可能发生的变化。
COVID-19 crisis has changed dramatically mobility of entire countries. Location-based social network data can be used to study mobility during crises. Lockdown in Italy saw both local and national mobility fall near to zero. Nevertheless, no large displacement of population has been observed. Cities emptied not towards remote areas, but mostly to urban belts. 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 9th 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.
