There is something wrong with the system when race is the main factor.
In any case....40% students at UCB are Asian American (24% White). About 37% at UC Irvine, 44% at UCSD. This roughly reflects the demographic make up of the state - o don't think you'd get the same numbers in New Hampshire.
Many colleges have secret quotas for Asians and there's a lot of hiding behind the "holistic process," rather than transparency.
