Michigan residents have been ordered to "stay home, stay safe" for about three weeks now, part of an effort to help flatten the curve of COVID-19 cases, but how are we doing in Calhoun County and some other Michigan communities?

Data collected from mobile phones throughout the country are being used by at least two companies — Unacast and SafeGraph — to rate residents' adherence to social distancing and shelter in place orders. Results are broken down by state and county and updated regularly online.

Unacast, a company that uses anonymous device location data, map data and strategic intelligence for clients in the retail, real estate, tourism, transportation and marketing industries, is giving states and counties a letter grade with its "social distancing scoreboard."

The scoreboard compares current data to data collected before the pandemic. Each overall grade is determined by looking at changes in a state or county's "average mobility," changes in visits to "non-essential" places and differences in "encounter densities."

Data last updated Thursday by Unacast gave both the U.S. and Michigan a "B" grade for social distancing.

Here's a breakdown by county of how Calhoun County is following state orders according to data collected from the company.
