Number 34 (Story #4), May 15, 1991 by Phillip F. Schewe and Ben Stein BLACKS, HISPANICS, AND AMERICAN INDIANS constitute 22% of the U.S. population but only (in 1988) 4.4% of the 4.5 million people identified as natural scientists or engineers, an imbalance which a number of scientific societies and government agencies are trying to correct. The NSF is instituting a number of programs (scholarships, teacher training, science day camps) aimed at increasing the number of minority PhD's in science and engineering from the current 350 per year to 2000 by the end of the decade.
