For many health care workers, the gender pay gap has grown. You can see in this Washington Post infographic how female physicians and dentists have been affected:
A new study published in the Journal of the American Medical Association (JAMA) reports that in 1980 male physicians were paid 20% more annually–a $33,840 total– than the women doing the same job. Now the gap has grown to 25.3% or a $56,019 difference. Similarly, the gender pay gap for female dentists and other health care workers has also widened but not for pharmacists and health insurance executives.
A 2011 Business Insider infographic presented some potential causes for the gender pay gap. We should note, though, that the JAMA study researchers accounted for any hours differences and for experience but not for specialties where females tended to select the lower paying areas like pediatrics. They also asked whether the pay gap was from unequal opportunities or female occupation preferences.
Sources and resources: Summarizing the JAMA study (gated), The Washington Post was also the source of the above infographic. You can see the first page of the study here and then Business Insider has several infographics that provide a historical context for the gender wage gap.
