"The new study found that Black residents in counties with more Black physicians — whether or not they actually see those doctors — had lower mortality from all causes, and showed that these counties had lower disparities in mortality rates between Black and white residents. The finding of longer life expectancy persisted even in counties with a single Black physician."

@luckytran My first impression upon reading the paper is that likely one of the reasons is that Black physicians move to counties where Black people have higher life expectancy. Is there something in the study that tries to exclude that explanation? (FWIW the limitations section drily says "The associations identified between Black representation and the study outcomes do not imply causation")
