Ferdinando Monte releases policy paper “Mobility Zones”

Posted in News

Ferdinando Monte released today a working policy paper constructing 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.

Monte computes 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 slightly grown at the onset of the epidemic and have sharply shrunk afterwards. Pre-Covid-19 Mobility Zones may be useful in calibrating quantitative studies of targeted restriction policies, or for policymakers deciding on the adoption of specfic mobility measures. Two examples suggest the use of Mobility Zones to inform within-state differences and cross-state coordination in mobility restriction policies.
