(Reuters Health)—When it comes to U.S. doctors’ paychecks, race and gender may be factors, according to a new study.
“Black male physicians earn substantially less than white male physicians, while white and black females have comparable salaries,” says senior author Dr. Anupam Jena, of Harvard Medical School in Boston. “Black and white female physicians both have lower incomes than either black or white male physicians.”
In a paper published online June 7 in the BMJ, Jena and his colleagues say there is limited evidence about race-based difference in physician incomes. But national estimates from 2011 show people in non-Hispanic white households earning an average of $76,063 per year, compared with $47,255 per year among people in black households.
A larger body of evidence suggests that female physicians earn less than their male counterparts, however.
For the new study, the researchers used data from two surveys of physicians. One was conducted between 2000 and 2013 and involved 43,213 white males, 1,698 black males, 15,164 white females and 1,252 black females. The second, conducted between 2000 and 2008, involved 12,843 white males, 518 black males, 3,880 white females and 342 black females.
Overall, race played a factor in how much male physicians got paid, with white males paid more than their black colleagues. Race was not a factor among female physicians, but they were paid less than their male colleagues.
For example, half of the white males were paid at least $253,042, while the median income for black males was only $188,230. White females had a median yearly income of $163,234, compared with $152,784 for black women.
Jena told Reuters Health that possible explanations include workplace discrimination, differences in negotiating pay and preferences in where people choose to work.
One researcher who wasn’t involved in Jena’s research, but is familiar with the data, says the findings are more likely due to what type of medicine participants practice, rather than race.
“The real issue that’s driving their results is that there are many more white specialists than black specialists, and specialists make a lot more money than primary care physicians,” says Dr. William Weeks of The Dartmouth Institute in Lebanon, N.H.
The question is whether black doctors choose not to go into specialties or if there are barriers keeping them from those fields, says Weeks, who is also affiliated with Aix-Marseille University in France.
Jena, however, said doctors’ specialties only explained part of the income gap.
