What is the total number of graduate degrees in the U.S.?

The answer is just under 11%. That according to a 2012 study by the U.S. Census Bureau. The data was taken from U.S. men and women over the age of 25 who had graduate degrees. The same 2012 report showed that 30% of Americans had at least a bachelors, showing a 20% drop from undergraduate to graduate degrees.

Just to compare, only a decade before, just 8.7% of Americans had graduate degrees. The 4% increase shows a steady growth among degrees being issued.
