It's not a secret; Google tracks our movements non-stop. When you "Google" something, YouTube, if you have an Android phone, smartwatch, Gmail, Google Maps, etc... you are telling Google where you are because of its geotagging capabilities. It is impressive. Google can aggregate our geotagged data while anonymizing it to exclude personal information.
Google's goal was to help answer the question if we are social distancing or not? This mobility report is phenomenal. Google is giving the world a brighter look at exactly how much it knows about people's movement leveraging the coronavirus pressure as an opportunity to repackage its tracking arsenal. This latest effort comes as Google and "big tech" partner up with government officials amid the COVID-19 pandemic.
Google's reports help us realize that we are going out less, but not as much as we would expect, particularly for non-essential industries. Mobility trends for retail and recreation in the U.S. for places like restaurants, cafes, shopping centers, theme parks, museums, libraries, and movie theaters are down 49% compared to baseline before the shutdown. Transit stations like public transport hubs such as subway, bus, and train stations are down 54%. Parks are only 20% down.
