The diversity rationale for affirmative action continues to rule the day in admissions offices across American universities, including law schools. Yet, there is a striking degree of uniformity about what actually constitutes “diversity. This Article examines the costs of such a uniform conception of diversity and explores the result of having some law schools being willing to admit student bodies that are just as diverse in white/minority terms but where the minority groups are not divided evenly. 21 Asian Am.

The purpose of this Study is to empirically examine the diversity of the legal profession. The primary distinctive features of this empirical analysis are that it evaluates diversity in the legal profession by (a) carefully comparing it against other prestigious professions that have significant barriers to entry, and (b) focusing on young individuals who recently began their careers. These distinctions are made to isolate anomalies that are more likely caused by forces specific to the legal profession rather than general social forces that limit the eligibility of historically disadvantaged groups to pursue prestigious employment opportunities. Further, by narrowing the focus to attorneys who recently began their careers, it gives a clearer picture of the current state of diversity. 47 Conn. L. Rev. 271 (2014)
