  • Analysis of mobile phone data in France showed that the March lockdown was effective in reducing population mobility, reducing countrywide displacements from 57 to approximately 20 million trips per day (65% reduction). Mobility drops were strongly associated with regions with active populations, workers employed in sectors highly affected by the lockdown, and hospitalizations. However, anomalous increases in long-range movements were identified before lockdowns were announced, and authors suggest these may act as seeding events if caution is not taken in timing the announcement of lockdowns.
