This is simply an aggregate (on country level) on how many people (as change to baseline) have been at what sort of location at what time (with a granularity of days): * Retail & recreation * Grocery & pharmacy * Parks * Transit stations * Workplaces * Residential It's quite clear that this can be easily derived from the information they have in maps.google.com plus phone movements. It's unlikely that this data presents any privacy concern. On the other hand it's probably mainly useless with regards to fighting Covid19. As the data is not detailed enough for such a purpose. Also I think we should point out that releasing this data in PDF form seems to be deliberate to prevent anyone else from providing meaningful insights by adding infographics of their own. [Edit: Clarification that does not contain number of people but simply difference to baseline]
