这份简短的说明构建了流动地带，以促进对控制COVID-19传播的个人流动限制的地理范围的讨论。移动区域是不相交的县集合，其中给定的个人移动水平直接或间接地连接每个集合中的所有县。我使用各县之间基于智能手机的移动数据计算美国和每个州的移动区域。流动区的平均面积和人口在疫情爆发前后急剧缩小。2019冠状病毒病前的流动区可能有助于校准针对性限制政策的定量研究，或有助于决策者决定采取具体的流动措施。两个例子表明，使用移动区域来告知州内差异和跨州协调移动限制政策。（C）2020 Elsevier B. V.保留所有权利。
This short note constructs Mobility Zones to facilitate the discussion on the geographic extent of individual mobility restrictions to control the spread of Covid-19. Mobility Zones are disjoint sets of counties where a given level of individual mobility directly or indirectly connects all counties within each set. I compute Mobility Zones for the United States and each state using smartphone-based mobility data between counties. The average area and population of Mobility Zones have sharply shrunk around the onset of the epidemic. Pre-Covid-19 Mobility Zones may be useful in calibrating quantitative studies of targeted restriction policies, or for policymakers deciding on the adoption of specific mobility measures. Two examples suggest the use of Mobility Zones to inform within-state differences and cross-state coordination in mobility restriction policies. (C ) 2020 Elsevier B.V. All rights reserved.
