NOTES: The Survey of Earned Doctorates (SED) was collected by calendar year in 1920–1957 and by academic year from 1958 on. Because the second half of calendar year 1957 is part of the 1958 SED, detail does not add to total. The sum of doctorates awarded in 1900–99 is actual and is the number percentages are based on. Percentages do not add to 100 because of rounding.
