New Jersey residents appear to be taking orders to stay home seriously.

Since March 12, the travel patterns for those in New Jersey have dropped from 3.83 miles per day to 1.45, a 62% decline as residents across the state reckon with the unprecedented threat created by the coronavirus.

Residents in Bergen and Somerset counties are the champions of self-isolation, according to the numbers from data intelligence firm Cuebiq. The median distance traveled by devices in both counties is 0.93 miles, the lowest in the state.

The information comes as a result of an analysis of anonymous cell phone data from 15 million people across the U.S. and was first reported by the New York Times. The numbers are intended to give an idea of how closely each area is following stay-at-home orders while understanding that much of the current travel is occurring for necessary errands, which do not violate orders to stay at home.

Daily travel appears to be dropping, even within the course of the pandemic. Every county in New Jersey saw a drop of at least 12% in the week from March 24 to March 30. The counties with the smaller declines also tend to be those in the southern part of the state, where necessary services such as grocery stores might require more travel to reach.

The decline in New Jersey is more stark than the U.S. as a whole. The average U.S. device was traveling 3.92 miles per day on March 12 and 2.33 miles per day on April 1, a 41% drop.

Eighteen of 21 counties in N.J. are below the current U.S. average.

Among states, New Jersey has 25,590 cases of COVID-19, the second most in the country and more than all but eight countries in the world.

On March 21, Gov. Phil Murphy signed the executive order closing non-essential retail businesses and ordering residents to stay home.
