The shift of women's attention away from traditional fields is being reflected in the college studies they choose, with a major trend toward business, according to a new Census Bureau study. "Women are choosing more realistic fields," said Rosalind Bruno of the bureau. "They're not very different from men now." The study found that between 1966 and 1978, the number of college women majoring in business jumped 300 percent, from 204,000 to 819,000, while the number majoring in education declined from 760,000 to 601,000. "They've gotten out of the traditional field of education into fields where they can have more longlasting careers now, not ones where they work a few years, then stop working, returning some years later," Bruno said. The study also found significant gains among blacks, whose college enrollment tripled between 1966 and 1978. Blacks also have shifted their emphasis. In 1966, the report said, some 40 percent were majoring in education or social studies. By 1978 this number had dropped to 17 percent. Business is now the most popular major for blacks, while the number in health and engineering fields showed significant growth. Overall, among the 9.8 million male and female total of students in college, business was by far the most popular major -- 1.9 million -- far outstripping education (781,000), English and the liberal arts (933,000 combined), health, medicine and biological sciences (1,175,000 combined), social sciences (763,000), engineering (565,000), physical sciences (193,000), math and statistics (142,000) and agriculture/home economics (144,000) as the most popular course. The number of students majoring in education and math and statistics declined by about a third, and physical sciences by about a sixth.
