The number of Medical Doctor degrees conferred in the U.S. has remained unchanged since 1985 – about 15,000 degrees a year. Therefore, the number of MD degrees conferred per U.S. resident has fallen since 1985 by the same rate as the growth of the population – about 25% cumulatively.

That period has also seen a significant increase in the median MD earnings, as measured by the BLS (Current Population Survey – CPS, Weekly & Hourly Earnings): In the decade between 2000 and 2010, physicians and surgeons have seen their nominal median income increase 51%, while lawyers saw an increase of 37%, and the average worker saw an increase of 30% (series LEU0254541000, LEU0254536800, LEU0252881500). The 30% increase, incidentally, represents a 2.5% inflation-adjusted increase according to the BLS.
