Google has published Community Mobility Reports that display the change in visits to places such as grocery stores and parks. The reports are created with aggregated, anonymized sets of data from users who have turned on the Location History setting. The aim of the reports is to provide insights into what has changed in response to policies aimed at combating COVID-19.
Available as pdf documents, the reports chart movement trends over time by geography, across different categories of places such as retail and recreation, groceries and pharmacies, parks, transit stations, workplaces, and residential.
