Now you've moved from saying I'm bad at math to calling me smug, and saying that I'm dismissing your data. I'm not dismissing your data; you have cited NO DATA.
Your first link referenced what amounts to a policy paper by the Detroit Regional Literacy Fund. Which is actually interesting because it implies the link goes to a study by the National Institute for Literacy.
As an aside, I'm not doubting the reputation of the National Institute for Literacy. I just don't trust any study I can't see the data from. This is a personal thing, but it comes from working and being friends with people that routinely manipulate data for Federal Policy Think-Tanks.
So first you have the Huffington Post with two sources, one that doesn't have any references in it and makes statements without visible justification and another that is The Wall Street Journal. Second, you've got a Yahoo Voices article: Your second link listed these sources: www.proliteracy.org, The Washington Post, Wikipedia, BBC News and the Associated Press. So you've got publications sourcing other publications.
The reason I don't immediately trust everything on the Huffinton Post and periodicals that don't actually source any studies AT ALL, is because they often draw inaccurate conclusions from bad data, or use sources that have no scientific grounding.
This happens a lot with medical studies.
The other problem is you seem to be assuming that the unemployed population is the same as the illiterate population. I don't know why you assume this, as your sources don't have any causative inferences.
Detroit has high illiteracy. Detroit also has high unemployment. Without a study, though, there is no implied causation.
If all you want is a citation from a periodical, I can do that: how about this that says 53% of recent college graduates are un- or underemployed?
