In this study, we set out to understand how the changes in daily mobility of people during the first wave of the COVID-19 pandemic in spring 2020 influenced daytime spatial segregation. Rather than focusing on spatial separation, we approached this task from the perspective of daytime socio-spatial diversity - the degree to which people from socially different neighbourhoods share urban space during the day. By applying mobile phone data from Greater Stockholm, Sweden, the study examines weekly changes in 1) daytime social diversity across different types of neighbourhoods, and 2) population groups' exposure to diversity in their main daytime activity locations. Our findings show a decline in daytime diversity in neighbourhoods when the pandemic broke out in mid-March 2020. The decrease in diversity was marked in urban centres, and significantly different in neighbourhoods with different socio-economic and ethnic compositions. Moreover, the decrease in people's exposure to diversity in their daytime activity locations was even more profound and long-lasting. In particular, isolation from diversity increased more among residents of high-income majority neighbourhoods than of low-income minority neighbourhoods. We conclude that while some COVID-19-induced changes might have been temporary, the increased flexibility in where people work and live might ultimately reinforce both residential and daytime segregation.
在本研究中，我们着手了解2020年春季新冠疫情第一波期间人们日常出行的变化如何影响白天的空间隔离。我们并非关注空间分隔，而是从白天社会空间多样性的角度来处理这项任务，即来自社会不同社区的人们在白天共享城市空间的程度。通过应用瑞典大斯德哥尔摩地区的手机数据，该研究考察了以下两方面的每周变化：1）不同类型社区白天的社会多样性；2）人群在其主要白天活动地点接触多样性的情况。我们的研究结果显示，2020年3月中旬疫情爆发时，社区白天的多样性有所下降。城市中心地区的多样性下降明显，且在社会经济和种族构成不同的社区存在显著差异。此外，人们在白天活动地点接触多样性的减少更为显著且持续时间更长。特别是，高收入多数族裔社区居民与多样性的隔离程度比低收入少数族裔社区居民增加得更多。我们得出结论，虽然一些由新冠疫情引发的变化可能是暂时的，但人们工作和生活地点灵活性的增加最终可能会强化居住隔离和白天的隔离。
