The Post analyzed GPS data from 18 million cellphones provided by SafeGraph to determine how often Americans were staying home on a county level.
The analysis reveals Americans are largely staying home even as some governors begin to relax social distancing restrictions. On average, people stayed home 89 percent of the time in the seven-day period ending April 30, slightly down from 93 percent for the week ending April 7.
Still, county-level data varies greatly by geography, with the highest rates of staying home seen in the East and on the West Coast, and in large cities like Chicago and Detroit.
Here is a breakdown of counties where Americans spent the most time at home in the week ending April 30, based on the Post‘s analysis. The list is limited to counties in which residents stayed at home at least 95 percent of the time or more.
