Have enrollments in traditional liberal arts fields dropped? Debates over the issue turn up everywhere, and Nate Silver -- the popular New York Times analyst of polling and statistics -- has taken up the issue. He argues that it all depends how you frame the question. If you ask whether certain majors are less popular, you may find that they are relative to other majors. But part of that is because the college population has expanded over time, with many of those going to college -- who might not have in earlier generations -- picking practical majors. But if you look at the percentage of all college students majoring in a given field, you may get a different figure. So, for example, English majors as a share of all majors have fallen in recent years, but English majors as a percentage of all college students have been relatively constant.
