There is little doubt that Asians boast, on average, the strongest academic profiles of any demographic group. A 2009 study by the National Center for Education Statistics reported that Asian Americans had an average GPA of 3.26, significantly higher than whites, who came in second at 3.09. The same trend holds in SAT scores.
That Asians perform so well means, by definition, that they suffer disproportionately from college diversity policies. After all, these policies aim to promote racial and ethnic diversity, even if that means admitting students with weaker academic profiles. Asian-Americans are most likely to be crowded out for the sake of diversity.
