I looked up a table on normal distributions, so I need to correct those last figures, as I was confusing location at either end of the bell-shaped curve with location at one end of it. IQ of 100 or above represents above the average for whites, one standard deviation above the average for blacks: this is 50% of whites, 16% of blacks. IQ of 115 or above represents one standard deviation above the average for whites, two standard deviations for blacks: this is 16% of whites, and 2.3% of blacks. IQ of 130 represents two standard deviations above the average for whites, three standard deviations for blacks: this is 2.3% of whites, 0.13% of blacks.

And if what I have read about Asians in America being a half a standard deviation above whites on IQ is correct, then the equivalent figures for them are as follows: IQ above 100, 69%; IQ above 115, 31%; IQ above 130, 7%.
