LOS ANGELES - For weeks Californians throughout the state have been staying at home, physically and socially distancing themselves from others in order to prevent the spread of COVID-19.
But is social distancing really working? And are we doing it well?
According to data collected by Unacast the state of California received a D- grade in terms of social distancing.
According to Unacast the grade is based on three elements: change in average mobility, change in non-essential visits and difference in encounter density.
"Encounter density" looks at the proximity between any two users within 50 meters over an hour period, according to Unacast's methodology.
A breakdown of the grade shows California had a 25% to 40% ‘reduction in average mobility’, which is based on distance traveled according to Unacast. This gave the state a D rank. The state received an F grade for having a ‘less than 55% reduction in non-essential visits’ and a D grade for having 40% to 74% ‘decrease in encounters density compared to national baseline’.
Twelve counties received an F grade including Los Angeles, Sacramento, Ventura, Riverside and Fresno. Orange County and San Bernardino counties received a D- grade.
No A’s were given and the only B grade was for Mono County.
Nationwide, Washington, D.C. is the top-performing state with a “C” grade. Residents there have decreased travel between 40 and 55 percent.
Alaska, South Dakota, North Dakota, Maine, Vermont, and Nevada were the next highest-performing states earning "C-" grades.
To collect the data, Unacast says it used tens of millions of anonymous cell phone records and their interactions with each other in order to ensure user privacy.
