Here’s How Well Oakland County Complies With Stay-At-Home Order

OAKLAND COUNTY, MI — As the spread of coronavirus accelerated in recent weeks, more and more Americans have come under state or local stay-at-home orders and advisories, until this past weekend more than 95 percent of the population was affected.

The purpose of these orders and advisories is to minimize the spread of the virus, which is highly contagious, although the scope of the orders varies by state and locality. Compliance with them varies widely, too, as Google has demonstrated with its community mobility reports, and by the business data firm Cuebiq, which compiled its COVID-19 Mobility Insights. Both aggregate location data from cellphones to track the movements of large numbers of people.

The data is aggregated and anonymized, Google said, so that individuals are not tracked by identity.

As of March 29, Google reports that nationwide movement to retail and recreational locations, including restaurants, shopping centers, movie theaters and the like, dropped 47 percent against a baseline set for the weeks Jan. 3 to Feb. 6.

Travel to groceries and pharmacies fell 22 percent; to parks, to beaches and gardens 19 percent; to transport hubs such as bus and train stations, 51 percent; and to workplaces 42 percent. Mobility to places of residence showed the only increase, of 16 percent.

In Michigan, which has been under a stay-at-home order since March 24, compliance was higher in every category except for parks, which saw a 15 percent increase in the state. Across the nation, movement to parks is down 19 percent.

As of March 29, Google reports that statewide movement to retail and recreational locations, dropped 58 percent against the baseline. Travel to groceries and pharmacies fell 28 percent. Travel to parks, beaches and gardens increased by 15 percent. Travel to transport hubs and similar locations dropped 55 percent; and to workplaces it increased 43 percent. Mobility to places of residence increased 12 percent.

Here is how compliant Oakland County has been compared to Michigan as well as the rest of the nation:

In general, compliance is higher in urban areas of the Northeast, upper Midwest and West Coast than in rural areas, the South and the Great Plains.

The data comes with several important caveats:

• Tracking location does not show how often or how closely people come into contact with each other, and is not necessarily a predictor of infection.
• Rural residents often must travel farther to get groceries or other necessities, while city dwellers don’t have to move far to infect others.
• Higher-income residents often are able to comply more easily than low-income residents, whose jobs do not always allow them to work from home.

But public health experts agree that abiding by stay-at-home orders and advisories is critical to slowing the spread of the virus, or in “flattening the curve” of infection. Such measures are deemed so important that authorities have instructed police to break up large gatherings of people, and even begun arresting those who violate stay-at-home orders.
