I must be reading it wrong, because I see 8.4% unadjusted for high school graduates in Nov 2011. How are you calculating aggregate regardless of higher level education? I don't understand how you can just add the high school, some college, and bachelors to get 20%.

That is exactly what I did. In my original response, I wrote aggregate unemployment for anyone who holds a HS diploma (regardless of higher level education) is 20%. I wasn't trying to be misleading, I just thought it was interesting to see that the aggregate for all non-high school dropouts.
Anyway, after looking at the article again, the author claims the unemployment stats come from 2009-2010 US Census and a study done at the Georgetown Center on Education and Workforce, broken down by age group. The BLS scope is obviously much larger and current.
