About the data from the Unacast website:
From our High-quality GPS Data, using the change in average distance traveled from pre-COVID-19 days as a proxy, we determined a "Social Distancing" score for each state and county: • A: >40% decrease • B: 30-40% decrease • C: 20-30% decrease • D: 10-20% decrease • F: <10% decrease or increase
