To determine how social distancing has influenced where people go in every state, 24/7 Wall St. analyzed mobility data from Google. Google’s mobility database covers for every state changes in mobility from Google’s baseline for every day between Feb 15 and June 15. This data is updated every 2 to 3 days. The baseline is the median value, for the corresponding day of the week, during the 5-week period Jan 3 – Feb 6, 2020. The baseline represents a typical amount of travel for a region over the five weeks between Jan 3 and Feb 6, 2020.
We calculated for every state average changes in daily mobility in six categories — residential, retail and recreation, grocery and pharmacy, parks, transit stations, and workplaces — over the five weeks ending June 12, 2020.
Google does not share absolute visitor numbers. Google’s calculations are based on data from Google users who have opted-in to Location History for their Google Account. Because the data represents a sample of Google users, the calculations may or may not represent the exact behavior of a wider population.
Data on COVID-19 case counts came from state and local health departments and was adjusted for population using data from the U.S. Census Bureau’s American Community Survey.
