\1\Excludes mathematics and computer science.
\2\Distribution by race/ethnicity based on U.S. citizens and those with permanent visas only.
\3\Does not include Native Hawaiians or other Pacific Islanders.
NOTE: Longitudinal comparisons by race/ethnicity should be done with extreme care, due to periodic changes in the survey. In particular, large numbers of Asians converted from temporary visas to permanent visas in the mid 1990s. The classification of degrees by field used in this survey differs somewhat from that in most publications of the National Center for Education Statistics (NCES). Includes physics, astronomy, chemistry, and earth, atmospheric, and marine sciences. The number of degrees also differs slightly from that reported in the NCES "Completions" survey. Detail may not sum to totals because of rounding.
