"In January, 2.8 million persons were marginally attached to the labor force, essentially unchanged from a year earlier. (The data are not seasonally adjusted.) These individuals were not in the labor force, wanted and were available for work, and had looked for a job sometime in the prior 12 months. 2.8 million were not counted as unemployed because they had not searched for work in the 4 weeks preceding the survey."
That's HOW they are cooking the numbers, by not counting millions of unemployed Americans!!!
The only people being counted are people receiving unemployment.
I would be willing to bet the 16.3% figure you give is probably too low, but closer to reality than the 11%.
