According to cellphone data, Hawaii appears to be one of the best states in the nation at complying with stay-at-home orders.
By recording smartphone GPS data, telecommunications companies have access to endlessly updating logs of where phone users have spent their time — data which some companies, including Google, have used to determine which countries, states and counties are most assiduously avoiding public places.
According to a report by Google, cellphone location data at retail and recreation services fell by 48% throughout the state between March 19 and April 30, compared to a baseline established before the COVID-19 pandemic.
Similarly, attendance at grocery and pharmacy locations, parks and workplaces declined by 25%, 57% and 46%, respectively during the same period.
Hawaii County residents did slightly better than the state in most categories, with a 51% reduction at retail, and a 68% reduction at parks.
Comparatively, the City and County of Honolulu had reductions of only 44% and 48% in the same categories.
The state was trending above the national average, which has seen retail attendance drop by 34%, grocery by 9%, and parks by only 7%.
Another company tracking social distancing trends, Unacast, graded Hawaii’s adherence to social distancing as a C+, indicating about a 55% reduction in average mobility, nonessential visits and density of interpersonal encounters.
Hawaii County received a B- grade, indicating about a 65% reduction.
These grades placed Hawaii’s social isolation compliance at fifth-best in the nation, behind Nevada, Vermont, New Mexico and Arizona. Hawaii County is within Unacast’s top 25% of counties nationwide.
“It is amazing what Google and these companies can do,” Lt. Gov. Josh Green said at a press conference Wednesday. “Sometimes even a little scary.”
Green said the state has considered using similar geo-tracking technology to better track and enforce visitors to the island to ensure that they comply with the state’s mandatory 14-day quarantine.
