Google is revealing anonymized location data on the movements of people in 131 countries as a guide for public health officials during the coronavirus pandemic.

The reports, available in PDF format, show how visits to broad categories of places—such as retail and leisure establishment, grocery and pharmacy stores, and residential areas—have changed in the past two months. The data show median daily visits to those categories for the three days ending March 29, compared with the median number of visits between January 3 and February 6.
