Here's How Well New Jersey Is Complying With Stay-At-Home Order

NEW JERSEY — 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. As of Sunday, more than 300 million Americans in 41 states — including New Jersey — have been asked or ordered to stay home.

New Jersey has shown that its compliance to stay-at-home orders is better than the rest of the country (see numbers below).

The need to stay home has become increasingly urgent now that the statewide number of cases has risen to 41,090, and 1,003 people have died. Read more: NJ Coronavirus Updates: Here's What You Need To Know

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.

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 New Jersey, which has been under a stay-at-home orders since March 21, compliance is higher in all of the categories.

As of March 29, Google reports that movement to retail and recreational locations dropped 59 percent against the baseline. Travel to transit stations fell 70 percent. Travel to workplaces fell 44 percent. Mobility to places of residence increased 16 percent. Travel to parks decreased by 36 percent. You can see the full report for New Jersey here.

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 shows.

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.

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.
