The San Antonio metro area earns a really unhealthy grade for social distancing, a data-gathering company says.

A widely used social distancing scoreboard from Unacast, a provider of location data and analytics, shows no county in the San Antonio metro area earns above a D for social distancing as of May 20.

Relying on a huge storehouse of cellphone data, the Unacast scoreboard measures social distancing activity on a daily basis in every state and county compared with activity before the coronavirus outbreak. The scorecard assigns a letter grade of A through F based on current social distancing behavior.

Each grade takes into account three factors:

• Percentage change in average distance traveled compared with the pre-coronavirus period
• Percentage change in visits to nonessential places compared with the pre-coronavirus period
• Decrease in person-to-person encounters compared with the national pre-coronavirus average

So, how did Bexar County fare in those three categories? On May 20, it received F's in all three categories. Why? Because it had less than a 25 percent reduction in average mobility (based on distance traveled), less than a 55 percent reduction in nonessential visits, and less than a 40 percent decrease in “encounters density” compared with the national average.

The scoreboard indicates Bexar County’s grades have bounced around. On April 11, for example, the county received a B for a 55 to 70 percent drop in average mobility.

Elsewhere in the area, Bandera County earned a D, the highest grade of any county in the state’s four major metros. Atascosa and Medina counties eked out grades of D-, while the remainder of the area’s counties (Comal, Guadalupe, Kendall, and Wilson) wound up in the F column.

In Texas, the San Antonio metro area isn’t alone in its apparent failure, at least recently, to adhere to social distancing guidelines.

On May 20, not a single county in the Austin, Dallas-Fort Worth, or Houston metro areas earned higher than a D- on the Unacast report card.

All five counties in the Austin area earned an F, and all 13 counties in Dallas-Fort Worth received F's, according to the scoreboard. Only one county in the greater Houston area earned above an F.

But, as with Bexar County, other metro areas’ scores in individual categories have fluctuated over time. Here are a few examples:

• On April 4, Travis, Dallas, and Harris counties earned an A for at least a 70 percent reduction in nonessential visits.
• On April 11, Tarrant County received a B for a 55 to 70 percent drop in average mobility.

The scores for the state’s major metros appear to reflect the recent loosening of stay-at-home restrictions across Texas. But health experts still recommend sticking with social distancing measures to slow the spread of the coronavirus. In fact, Unacast points out that the World Health Organization and the U.S. Centers for Disease Control and Prevention (CDC) cite social distancing as the “most effective way” to combat coronavirus infections.

Unacast says it launched the social distancing scoreboard in March to enable organizations to measure and grasp the efficiency of local social distancing efforts.

“Data can be one of society’s most powerful weapons in this public health war,” Thomas Walle, co-founder and CEO of Unacast, says in an April 16 release.
