Washingtonians are starting to crack.

After five weeks under stay-at-home orders, D.C.-area residents are slipping out of their homes more often, despite a gradual uptick in confirmed COVID-19 cases, according to smartphone data.

After earning an “A” in mobility reduction on Unacast’s Social Distancing Scoreboard at multiple points in April, the District has been hovering around a “B” this month. Virginians and Marylanders are faring slightly worse, earning mostly “C” grades in May so far.

Similar trends are seen in data from the University of Maryland, which shows slight downturns in social distancing in all three jurisdictions since the middle of April.

The numbers vary from county to county, however. In Maryland, for example, Montgomery County is better at staying home than Prince George’s County, which may reflect a higher number of front line workers in the latter. In Virginia, Arlington County has hit “A” levels all month, where Prince William has earned mostly C’s.

Both the University of Maryland and Unacast draw their numbers from smartphone data that tracks users’ locations.

Washingtonians made headlines in recent days when they rebuffed social distancing rules to watch an airshow on the National Mall and pick up their Cinco de Mayo margaritas outside local Mexican restaurants.

“Well, I found everyone in Montgomery County,” local reporter Abby Isaacs tweeted on Cinco de Mayo. “They’re at Uncle Julio’s at Rio trying to get tacos.”

Perhaps not coincidentally, Unacast’s Social Distancing Scoreboard gave D.C. a “C” on May 5.

But overall, data suggest that Washingtonians are staying at home in greater numbers than the rest of the country. In April, 53% of D.C. residents stayed home, according to the University of Maryland’s tracker, making it the most socially distant jurisdiction in the country, followed by New York and New Jersey.

Maryland and Virginia fared worse, with 39% and 34% of residents staying home in April, respectively. That percentage could begin to slide downward as governors Larry Hogan and Ralph Northam announce plans to gradually reopen businesses, golf courses, and parks in the states.

D.C. Mayor Muriel Bowser has not announced a reopening date for the District, saying this week that she intends “to do what’s best for our jurisdiction.”
