Income for most medical students, those who are white and Asian, is shifted greatly to the right. This usual shift is to the more horizontal broad income distribution of Vietnamese and black (and likely rural students). Without the Vietnamese component in the All Asian category, the Asian curve would exceed the white and more closely resemble the Indian/Pakistani. Asian students are a combination of factors favorable to admission including highest income, education, professional parent, and college preparation levels.
