Respondents in the 2000 Census 1% Sample were asked if they have any mental disability. Prevalence grows with age, so I limited the sample to people ages 30 to 49. Here are the percentages who answered yes by race/ethnicity:
Percent with mental disability (sample size = 847,061)
American Indian 7.6
Puerto Rican 6.1
African American 4.8
Scotch Irish 3.4
French Canadian 3.2
Asian Indian 1.0
Each estimate is based on hundreds if not thousands of respondents.
Those from mainlaind Southeast Asia tend to have the highest rates. Mental disability is also prevalent among American Indians, Eskimos, Puerto Ricans, and blacks.
Most European-descended people are in the middle; southern Caucasians tend to be lower.
Eastern and Southern Asians have low rates, as do Hispanics (not from the Caribbean) and black immigrant groups. Most immigrants groups look good--these data again reinforce the view that non-Caribbean Hispanics are comparatively healthy--but I wonder if SSI fraud inflates the percentages among some groups (I know there are restrictions if you are not a citizen). The data do not support the liberal view that racist America drives immigrants crazy.
