More Blacks Die of Covid-19 Partly Due to Greater Use of Public Transit

(p. A7) African-Americans may be dying at higher rates than white people from Covid-19, the disease caused by the novel coronavirus, in part because of black people’s heavier reliance on public transportation for commuting, two new studies by economists suggest.

One of the studies, by University of Virginia economist John McLaren, found that the racial discrepancy remained even after controlling for income or insurance rates. Instead, Mr. McLaren found the gap was due in part to the fact that black workers are more likely to get to work via public transit, including subways and buses.

About 10.4% of black commuters take public transit, versus 3.4% of white commuters, according to the Census. After controlling for the use of public transit, Mr. McLaren finds the racial disparity in Covid-19 deaths is less pronounced.

The other study, by Christopher Knittel and Bora Ozaltun, both of the Massachusetts Institute of Technology, found that a 10% increase in the share of a county’s residents who use public transit versus those who telecommute raised Covid-19 death rates by 1.21 per 1,000 people when looking at counties around the U.S.—or by 0.48 per 1,000 people when focusing only on counties within individual states. In their analysis, the researchers controlled for race, income, age, climate and other characteristics.
