Unacast, a human mobility data company, developed a social distancing scoreboard as part of its COVID-19 Toolkit to grade states on how well people in each state are keeping their distance from others during the coronavirus pandemic.
The scoreboard uses its data from tracking mobile phone locations to gauge how far people in each state traveled on March 22 as compared to an average Sunday. States with at least a 40 percent drop in the distance traveled received an A, according to the Chicago Tribune.
Here are the 18 states that received an A in alphabetical order:
1. Alaska
2. California
3. Connecticut
4. Delaware
5. District of Columbia
6. Florida
7. Illinois
8. Maryland
9. Massachusetts
10. Michigan
11. Minnesota
12. Nevada
13. New Hampshire
14. New Jersey
15. New York
16. Pennsylvania
